ABSTRACT
The 18th Nov 2011 Visakhapatnam sky was the Darkest of the year, and the Hunter belt stars are very significant in this dark sky scenario. Does the Dark matter is emitted by the Sun or is it of a cosmic origin is one of an intriguing subject matter of a debate. The Gray sky and the Sun in a hazy atmosphere with considerable reduced brightness and so could easily be image captured of its spectrum on 20th Nov 2011. The difference between black shadow of the Moon on the Sun and the Dark sky scenario has a pointed difference. The former as observed earlier by the present author gives rise to peculiar rays filtered and modified through the constituents of the Moon interior. While the Dark sky scenario possibly generated by the Sun or the Cosmic Sagittarius Constellation group of Stars during 24-25th November 2011. The Hunter in a Gray sky scenario at the early morning of 29th Nov.2011 is very striking. And especially the Sun spectrum at Zenith at mid-day 30th Nov 2011 captured with about a set of six filters shows the amazing Green band like ring asserts that the CME hurled into space at about 930 km/s (2 million mph) generated on the 26th Nov 2011 the same explosion that caused the radiation storm have penetrated through the D-layers of terrestrial ionosphere and caused the background weather scenario vividly captured in my digital images.

INTRODUCTION:
The few days following the 14th November 2011 the Visakhapatnam weather was very warm. The chilly winds of the NE Monsoon are blowing slightly in the evening time and early mornings the cold winter was experienced. CNN update 0745 GMT (1545 HKT) says Search teams combed through rural South Carolina on Thursday morning after a storm swept through the Southeast and In North Carolina, an apparent tornado south of Winston-Salem damaged "multiple structures." Daniel Griffiths BBC news reports. 17 November 2011 last updated at 03:08 GMT Scientists studying the solar system say they have found the best evidence of water out there. It is just beneath the surface of Jupiter's icy moon, Europa and liquid water could represent a potential habitat for living organisms. Britney Schmidt says from models of magnetic forces, and images of its surface, scientists have long suspected that a giant ocean, roughly 160km (100 miles) deep, lies somewhere between 10-30km beneath the ice crust.
Swedish news papers gave that “Freezing rain and snow is expected to fall across large swaths of central and northern Sweden on Friday Nov 18th, 2011 night, prompting warnings from icy road conditions across much of the region.” SMHI has issued a class 2 warning for northwestern Sweden ahead of the extreme weather conditions set to hit Sweden as Berit rolls across the country after wreaking havoc in neighboring Norway.
Space Weather.com gives “As northern winter approaches, darkness is enveloping the countries of the Arctic. In fact, yesterday in Tromsø, Norway, night fell less than ten minutes after sunrise. Fredrik Broms photographed the sun during its few minutes above the horizon: on November 22nd 2011 with a goodbye.” This splendid photo by Fredrik Broms has a copy right and cannot be reproduced.
CME: Energetic protons, which make up the bulk of the storm, were accelerated in the Earth’s direction earlier Saturday 26th Nov.2011 by shock waves in a CME racing away from the sun at about 1000 km/s (2.2 million mph). The CME itself will reach Earth on Nov. 28th around 14:23 UT (+/- 7 hours). The cloud could trigger geomagnetic storms when it arrives on Monday. High-latitude sky watchers should be alert for auroras. A radiation storm that began on Nov. 26th when a magnetic filament erupted on the sun is subsiding. Nevertheless, the Earth-effects are just beginning. The same explosion that caused the radiation storm also hurled a CME into space at about 930 km/s (2 million mph) the later is expected to reach the Earth by17:21UT+/-7hours according to GSWL, USA.
Andhra Pradesh
The star Aldebaran (Rohini), as it seems to follow the Pleiades or Seven Sisters star cluster (Kanya Rasi in Hindu Astronomy) across the sky. Aldebaran is also known as Alpha Tauri (Vrishabha Rasi). In rayalseema of Andhra Pradesh the winter has set in and minimum temperatures have fallen down since 23rd Nov. 2011. In Kurnool district Wednesday morning very low temperature was recorded about 15deg C while the noon temperatures prevailed at 29 deg C. The humidity varied from 32% to about 87%. Winds were blowing about 4km/hr to about 10km/hr Anathpuram district recorded from 19 to 28 deg C with humidity 33% to 86% and winds blowing at the rate of 9 to 12km/hr. In Kadappha district temperature was from 18 to 28 deg C with considerable humidity up to 90% in the morning and in the noon it was at 57% Due to this winter chill weather has been experienced. The winds were blowing at 4 to 15kms/hr. That is why the Kadappha experienced more severe winter. In Chittoor district the the temperatures were from 24 to 41 deg C with humidity from 56% to 86% and winds had speeds from 6 to 10kms/hr. Drop in minimum temperature by 1-2 degree Celsius has been recorded in Punjab, Haryana, Delhi, Uttar Pradesh and north Rajasthan in the 24 hours of 23rd Nov 2011. Moderate fog is expected over parts of Punjab, Haryana, Delhi, west Uttar Pradesh, north Rajasthan and in isolated pockets of east Uttar Pradesh and Bihar during the next 24 hours. A bulletin from Meteorological Centre here today said the temperatures were below normal at one or two places over Telangana but above normal at one or two places over Coastal Andhra Pradesh and Rayalaseema. The lowest minimum temperature of 12 degrees Celsius was recorded at Adilabad. Isolated rain occurred over coastal Andhra Pradesh and Rayalaseema. The weather has been dry over Telangana. The chief amounts of rainfall recorded in cm are Tada (Nellore dist) 6, Sriharikota (A) (Nellore Dist) 5, Tirupati AP, Satyavedu (Chittoor dist) 4 each, Srikalahasti (Chittoor dist), Tirumalla (A) (Chittoor Dist) 3 each, Puttur (Chittoor dist), Sullurpet (Nellore dist), Tirupati (A) (Chittoor Dist) 2 each and Chittoor one. Nov 24th 2011 news: Tamil Nadu adjacent Cameroon has a low depression due it the North East monsoon became active and West mid Bay of Bengal sea is blowing the eastern winds. Tamil Nadu has heavy rains and South Coast Nellore, Rayalseem and Chittoor districts have experienced heavy rains. In the last 24 hours of 24th Nov 2011 the rains recorded were 6cm in Thada, Tirupathi 4cms, Srikalahasti 3cms, Puttoor and Sulurpeta 2cms each and finally Chittoor recorded 1cm rain. Nellore experienced heavy rain from Saturday night to Sunday night about 25cms with Kyvalya, Kalinga and Swarnamukhi rivers overflowing. The sea incursions, heavy tide affected Nelatoor low lying areas with inflow of water in to the houses. Buckingham canal a significant military route of erstwhile East India Co. has been overflowing with an unprecedented record. Arabian Sea low depression was located at 350kms NW from Mangalore. Jayalakshmipuram villages submerged in water and in flow entered several houses. On Sunday Puttur 11cms, Venkatagiri tirumala 10cms, Srikalahasti 9cms, Satyvedu tirupati 6cms, and Atmakur 4cms rain was recorded. Tropical cyclone 05a was located approximately 165 nm west-southwest of Cochin, India. 05a will intensify slowly as it moves closer to a subtropical ridge axis until it encounters a trough currently moving east over Saudi Arabia, at which point it is expected to recurve over the northern Arabian Sea.
St. Cloud area: Snow and rain moved into the St. Cloud area as soon as Friday after a sunny and warm Thanksgiving Day. Temperatures in the range 44.8 to 50 degrees prevailed. Recorded high of 56, set in 1990, doesn’t appear to be in jeopardy, according to the weather service.
Moscow: On November 23rd, 2011 there were only about six hours of true daylight each day the sky not brightening until around 9 a.m. and dipping into twilight by 3:30. Heart of Moscow, in crisp winter air that seems to make the spotlights on the Kremlin towers shine with a hard clarity, is splendidly beautiful at night and it was a bitterly cold Saturday 26th Nov.2011.
The U.N. weather group said 2011, still with one month left, was the 10th warmest year on record. While the temperature was down from 2010, the WMO said it was higher than previous La Nina years. La Nina typically has a cooling influence on temperatures.
Astronomy:
It is Jupiter, king among worlds in our solar system and brightest object in the November 2011 night sky. Dazzling Jupiter totally stealing the spotlight this month almost in zenith by 9.00PM, as it shines bright from evening dusk until morning dawn in the fourth week of November 2011. Jupiter comes out at evening dusk all this month, but will set an hour or more before dawn by November’s end. After soaring to its highest point for the night, Jupiter found to descends into the western half of the sky. Jupiter is found setting in the west earlier each morning as November 2011 approaches December 2011.
Earth Tremors worldwide:
An earth tremor shook parts of the Greater Manchester area today.A two-second rumble was felt over a wide area of the city just before 9am, followed by a smaller tremor some 10 minutes later. The earthquake had measured between 2.5 and three on the Richter scale. The West Midlands last month, and which measured 4.8R on the scale. Around 10 such earthquakes would be expected in the UK each year. In eastern El Salvador in a 24-hour period the brief quakes, which started Thursday, ranged from 1.8 to 4.6 in magnitude. Two earthquakes hit Japan Thursday – a 6.0-magnitude earthquake near the crippled Fukushima Daiichi nuclear power plant and a 6.1-magnitude quake in the northern island of Hokkaido. Just in time for Thanksgiving dinner. The U.S. Geological Survey recorded a 3.7-magnitude quake about 3:11 p.m. Thursday near Prague. The epicenter was 17 miles northeast of Shawnee and 44 miles east of Oklahoma City. The quake was described as more of a boom than a rumble. An earthquake at 5.9R magnitude rocked India's northeast, Myanmar and Bangladesh on Monday 21st Nov 2011, triggering panic among the people. The tremor was felt at 8.47am in most parts of Assam, Nagaland, and Manipur, besides in Bangladesh and Myanmar. The epicenter was located in Myanmar, about 130 km east of Manipur capital Imphal. A mild earthquake measuring 3.4 on the Richter scale jolted Kerala's Idukki district which houses the Mullaperiyar Dam, on Saturday 26th Nov 2011 morning. Mullaperiyar Dam developed cracks following tremors last month. Andhra Pradesh several places experienced earth tremors of magnitude 2 to 3R around 7h50mPM on Sunday November 27th, 2011. It was felt in Guntur Vinukonda region around 7hh55mPm for about 3 secs. In Shavalyapuram it was felt at 7h50mPM and in Nujelandla Mandalam the Puvvada village felt the tremor around 7h50mPM and also it was felt in Kondalarayunipalem, Mulakuluur villages slightly. Nellore midnight, Guntur, Nalgonda, Nagarjunasagar Dam area and Prakasam district lingsamudhram region felt repeated earth tremors. On Sunday 27th Nov 2011 at 8h15mPM Mild tremors affected Nujendla, Savalyapuram and Vinukonda. The villages Komalapadu, Mamilapalli, Makanavaripalem and Patilivaripalem experienced mild tremors.
New Moon Eclipse of 24/25th Nov 2011:
It is seen from Invercargill in New Zealand. A partial eclipse of sun was observed on Friday from high latitudes of southern hemisphere and including South Africa, Antarctica, Tasmania and most of New Zealand. The greatest eclipse was at 1120 hours and ended at 1317 hours. McMurdo Station on Antarctica "The temperature is around 15°F, windy, and snowy," writes astronomer Chris Walker. Many of us associate solar eclipses with a blacking out of the Sun. It fell on Friday 2011. This Sagittarius new Moon partial solar eclipse occurred on November 24 at 10:10pm PST and on November 25 at 1:10am EST/ 6:10am GMT. It images for us the interplay of light and dark, good and evil, male and female, yin and yang. Mid-eclipse occurred at 6:10 UT, at which time all of Antarctica was experiencing a partial event that covered 40% to 90% of the Sun's diameter (75% at the South Pole). Jupiter is in Venus' sign of Taurus at this solar eclipse.
FINDINGS:
The weather in Visakhapatnam has changed since Friday 18th November 2011 to one of dense fog and in indoor people moved to rooms which are better protected and have the comfort of warmth preserved inside the rooms. The 18th Nov 2011 Visakhapatnam sky was the Darkest of the year, and the Hunter belt stars are very significant in this dark sky scenario. Does the Dark matter is emitted by the Sun or is it of a cosmic origin is one of an intriguing subject matter of a debate. The Gray sky and the Sun in a hazy atmosphere with considerable reduced brightness and so could easily be image captured of its spectrum on 20th Nov 2011. Contrasting is just the Sun in such an atmosphere and its glow through the haze. Does the haze also exhibit the affects of the X-ray and other radiations of the Sun? Possibly the Gray sky around the sun set is an indication of it. The Gray scenario of the sky persisted on 25th and 27th November 2011. What is that it makes certain clouds at a considerable height in the atmosphere to project the Gray scenario background? Are they particularly susceptible to the penetrating invisible rays of the Sun or its extreme Ultra Violet and the X-rays? What other possible rays would penetrate the D-layers of the terrestrial atmosphere? Of considerable interest is that the New Moon Night November 24th 2011 is regarded as a Black Day. The difference between black shadow of the Moon on the Sun and the Dark sky scenario has a pointed difference. The former as observed earlier by the present author gives rise to peculiar rays filtered and modified through the constituents of the Moon interior. While the Dark sky scenario possibly generated by the Sun or the Cosmic Sagittarius Constellation group of Stars during 24-25th November 2011.
IMAGES:
Fig.1 Moon captured on 17th Nov 2011 in a movie shows the spectra with a dominant red region just like the Sun set ring on 15th November 2011. The few days around 15th Nov 2011 were very warm at Visakhapatnam.
Fig.2 shows the 18th Nov 2011 Visakhapatnam sky as the Darkest of the year, and the Hunter belt stars are very significant in this dark sky scenario. Does the Dark matter is emitted by the Sun or is it of a cosmic origin is one of an intriguing subject matter of a debate.
Fig.3 shows the Gray sky and the Sun in a hazy atmosphere with considerable reduced brightness and so could easily be image captured of its spectrum on 20th Nov.2011 Contrasting is just the Sun in such an atmosphere and its glow through the haze on 22nd Nov 2011. Does the haze also exhibit the affects of the X-ray and other radiations of the Sun? Possibly the Gray sky around the sun set is an indication of it.
Fig.4 shows the Jupiter spectrum in its fineness of a bright glow. The dark background sky has reappeared on the 23rd November 2011. But in the early morning of 24th November 2011 the group of visible stars on the west and the East were in a Gray background of the sky scenario.
Fig.5 On the 25th Nov 2011 the Hunter constellation stars were observed in a dark-gray early morning around 4h08mAM. The Jupiter has given nice spectra with the sky somewhat clear in spite of the Chilly weather.
Fig.6 the low depression clouds have appeared glittering the sky scenario with their reflections and the around 21h22mPM on 25th Nov 2011 the sky was strikingly Gray. The reflection of the Sun shine from a window pane shows the changing pattern of the hues of the spectra obtained around 15h53mPM and again at 15h58mPM. Note the dominant Yellowish hue that dominated the spectrum around 15h58mPM. The Sun spectrum at 15h53mPM was remarkably fine without the Yellow preponderance. The Jupiter spectra obtained around 21h20m and 21h23mPM showed the noise spectral background of the cloudy weather. The study of the cloud characteristics using the Jupiter spectra would form an interesting topic of continued research.
Fig.7 shows the remarkable Gray background sky scenario with a good bright spectrum of the Sun in the afternoon around 15h42mPM on 27th Nov.2011. In this figure for the first time I have presented details of the Belt stars intensity profiles as image captured with 14.1MP canon camera IXUS130 that records my hand shake and so provided a series of the images in possibly micro-seconds occurrence if not in milliseconds. Thus they formed multi-shot image captures. The intensity profiles are remarkable that they exhibited a distinct, vivid and beautiful charming data each separately for the three different belt stars of the Hunter in Orion constellation. In India this month following the New Moon of 24/25th Nov 2011 is regarded as just the Month of Orion Constellation locally known as Mrigasira Rasi.
Fig. 8 shows the Hunter in a Gray sky scenario and the Sun spectrum at Zenith captured with about a set of six filters. The amazing Green band like ring asserts that the CME hurled into space at about 930 km/s (2 million mph) generated on the 26th Nov 2011 the same explosion that caused the radiation storm have penetrated through the D-layers of terrestrial ionosphere and caused the background weather scenario vividly captured in my digital images.
Fig.9 The Moon shine reflection in the beach sand and several such images in the wet sand of the crescent moon of 29th Nov.2011 have fascinating optical caustics. Jupiter shines bright in spite the CME and the radiation affected lower terrestrial atmosphere and stands as a glowing salute to the residence Narasimha Ashram. Its spectrum contains lot of noise information about the secondary effects of the 26th Nov 2011 solar explosion. The morning brilliant red Sun rise is worth a careful study as its spectrum has a broader red hue in a distinct style. The Yellow persists as an outer ring!
