ABSTRACT:

Seven Figures are presented in which the affects of the double CME and the Solar flares have been brought out by a spectral profile analysis. The claim of gray hue of the Bay of Bengal Sea even on the Full Moon Day of 13th August 2011 has been pointed out as due to the affect of X-Ray, Microwaves and the Ultra-violet radiations on the upper terrestrial atmosphere. It is an interesting finding of the Dark  deep-Blue hue of the twiligt at the time of Moon rise on the Full Moon day.

Key words: Ionosphere, Astronomy, Solar flares, double CMEs,Gray hue and Air Glows.

Introduction:

The August month began with a big bang of heavy showers in Andhra Pradesh. From 30th to Sunday morning rainfall were recorded as Parakala, Nizamsagar 13cm, Mulugu 12cms, Mahabhubhnagar , Hanumakonda 10cm, Kaikalur, Medak, Vikarbad 9cm.Paoannapeta, Kolcharam recorded 15cm rain. Pannapeta Ghannapuram project and Jahirabad rural area Nar-in-ja stream (vagu) are over flowing with flood waters. Hanumakonda recorded 91.6mm while Thorur recorded 90.4mm. Except Krishna, Anathpuram, Chittoor, Warangal, Guntur, and Nizamabad have only had reasonable rains but in about 17 districts the rainfall is far below the average. And on 31st July 2011 the Karnataka, Maharashtra, Goa, Konkan and in Kerala also there were heavy rains. The rains in the upper reaches of Srisailam and Nagarjuna helped good storage of water in those reservoirs and agricultural farming would have no problem of water supply. West Bengal, Eastern States, Gujarat and Madhya Pradesh had moderate rains but North India is experiencing in some regions very warm weather. Bihar and Jharkhand about 35 people died due to thunderbolt lightning. Bojapur three, Kathihar two, Rohathas, Arawal one each, in Bihar while in Jharkhand Palmavu, Lathehar and Gharva villages a total of nine people died.

The China 7th or so Typhoon Maifa is weakened as it moved towards North-East crossing over densely populated areas on the East-Coast on Sunday 7th August 2011 with 175kmh winds and moved at a speed of 25kmh. Made a Landfall on Weihai on 9th August 2011 over Shandon peninsula.

Earth is entering a stream of debris from Comet Swift-Tuttle, source of the annual Perseid meteor shower. International observers are now reporting nearly 20 Perseids per hour, a number that will increase as the shower reaches its peak on August 12-13. The best time to look is Saturday morning, Aug. 13, just before dawn when the Moon is low and meteor rates are peaking. Full moonlight will reduce visibility on peak night, but not enough to completely spoil the show.

On August 9th at 0805 UT, sunspot 1263 produced an X7-class solar flare--only the third X-flare of new Solar Cycle 24 and the most powerful so far. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash:

The brunt of the explosion was not Earth directed. Nevertheless, radiation from the flare created waves of ionization in Earth's upper atmosphere, briefly disrupting communications at some VLF and HF radio frequencies. The blast also accelerated a mild torrent of protons toward Earth. The CME will probably would miss the Earth. At this time, however, we cannot rule out a glancing blow from the flank of the cloud on August 11th or 12th. Solar wind: speed: 428.1 km/sec: density: 1.9 protons/cm3 ; Sunspot number: 43; X-ray Solar Flares: 6-hr max: C1 0746 UT Aug11, 2011; 24-hr: C1 0746 UT Aug 11, 2011: Solar wind flowing from the indicated coronal should reach Earth on or about Aug. 14th. X-ray Solar Flares; 6-hr max: C1 1729 UT Aug 10, 2011; 24-hr: C6 1044 UT Aug 10, 2011: Solar wind; speed: 482.7 km/sec; density: 1.8 protons/cm3: Sunspot number: 54. From Friday 12th August 2011 to Saturday morning rainfall recorded are at Bhadrachalam, Sriramnagar, Dhvaleswaram, Peddapuram, and in Kalingpatnam about 4cms, Prthipadu, Ranastala, Adilabad, and Kunavaram about 3cms.

Our Observations:

Beginning 1st August 2011 till the 14th August 2011 there were extensive rains in Hyderabad, North districts and in Telangana. The low depression formed on Friday 2011 August adjoining the West Bengal has moved away towards the Madhya Pradesh. Due to it the Visakhapatnam experienced heavy showers on Thursday and Friday. Throughout the fortnight of August Visakhapatnam sky was cloudy and the temperatures were below the average. The meteor showers have not been seen much on the coastal region of Andhra Pradesh. But the Sun was quite brilliant in spite of the cloudy weather with surprisingly cool weather. This is a new finding on the phenomenon of weather in Visakhapatnam, Both the Sun and Moon is found to be quite brilliant, throughout the fortnight of their observation. The happenings on the Solar surface of double CME occurrence and the Solar flare winds have definitely influenced the terrestrial atmosphere at particularly the lower levels of the ionosphere.

IMAGES:

Fig.1 shows the weather scenario at 18h34mPM and again at 19h17mPM with remarkable gray sky changed to blue hue. The image at 18h34mPM confirms the disappearance of the gray cloud along with its reflective hue of the sea. The image at 18h34mPM has the reddish clouds. A widespread display of auroras erupted late Friday, Aug. 5th, when a double-CME hit Earth's magnetic field and sparked a G4-category geomagnetic storm. "It was the most impressive display I've seen in years," reports Lance Taylor of Edmonton, Alberta. "From 10:00 PM on Friday to 3:00 AM on Saturday, the sky was pulsing from horizon to horizon in every direction." The show was not restricted to Canada. Northern Lights spilled across the border into the United States as far south as Utah, Colorado, and Nebraska. (Note: The faint red lights photographed in Nebraska are typical of low-latitude auroras during major geomagnetic storms.) Observers in Europe as far south as England, Germany and Poland also witnessed a fine display. Note that the reddish hue of the sky is not only due to the Sunlight refraction but also the affect of superimposed CME that has hit the Earth. The finding is that the affects persist for a few more than the immediate impact of it as observed in Nebraska by Lance Taylor of Edmonton, Alberta. Solar wind speed: 600.9 km/sec: density: 0.8 protons/cm3 : X-ray Solar Flares: 6-hr max: B8 1220 UT Aug 08; 24-hr: C1 0310 UT Aug08 : Sunspot 1263 poses a continued threat for X-class solar flares. Credit: SDO/HMI: The M9-class solar flare of August 4th produced a burst of shortwave static so powerful that receivers on Earth picked it up after sunset. "A Radio Jove observer in Florida recorded the burst when the sun was 38 degrees below the horizon," reports amateur radio astronomer Thomas Ashcraft. Ashcraft's own radio telescope in New Mexico recorded the event 1 hour and 54 minutes after sunset.

Fig 2 has a splendid display of green hue with beautiful yellow ring around the surface the left-over of debris from the double CME ejections from Sun on the 4th August 2011. The orange filter image shows the predominant red glow of the dust in the atmosphere. Surprisingly it shows the green hue as dominant over the blue hue of the Moon Sine Glow. The sky blue filter shows the subdued intensity profile of the blue hue.

Fig 3 shows on 8th August 2011 at 22h03mPM the green hue as dominant in spite that the blue hue persists at a low profile.

Fig 4 details that at 22h05mPM the green hue envelops the dominant yellow hue near to the Moon of the Moon Shine Glow. The light yellow filter also shows the yellow hue but with dominant green hue dispersion of the Moon shine air glow.

Fig 5 of the sun spectra with filters definitely gives the signature of the Terrestrial atmosphere hit by the Ultra Violet flash and the X-ray irradiation of the atmosphere on the 11th August 2011 morning time. The cloudy weather was very helpful to enhance and brighten the effects of the Ultra-Violet brushing flash of the Solar flare and the production of the X-ray bursts. SpaceWeather reported”that the CME will probably would miss the Earth. At this time, however, we cannot rule out a glancing blow from the flank of the cloud on August 11th or 12th.”

The images of Sun spectra image captured by me, on the 11th August 2011 at 10h10mAM, indeed show the brilliance of the spectra. Orange filter shows the brilliant Yellow hue of the Air-Glow.

Fig.6 Surprisingly both the Green and the light Yellow filters as well show up the Brilliant Yellow produced by the CME, Solar Wind of Protons and the X-Ray burst of August 9th at 0805 UT. The Sunspot 1263 produced an X7-class solar flare, only the third X-flare of new Solar Cycle 24 and the most powerful so far. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash. The radiation from the flare created waves of ionization in Earth's upper atmosphere briefly disrupting communications at some VLF and HF radio frequencies. The blast also accelerated a mild torrent of protons toward Earth. The CME was expected to probably miss the Earth. However, it cannot be ruled out, a glancing blow from the flank of the cloud on August 11th or 12th, the predictions by NASA asserts. What surprises me most is that the Sky Blue filter image obtained by me, of the Solar spectrum on 11th Aug 2011 at 10h10m AM has totally obstructed away, the Yellow brilliant glow of the Sun.

Fig.7 The Moon rise on the 13th August 2011 on the India festival day of Sravana Pournima has been one of good excitement. The Moon shine was very pleasant. This continued on the 14th August, 2011 also when the brilliant Moon was found enchanting. It should be noted that the Sravana Pournima is the day when sisters tie sacred knots on the forehand of the brothers and men of authority to protect them with utmost effort and valour. The other significant finding of this investigation is that the Gray Bay of Bengal hue has gradually changed with the predominant deep blue of the Moon shine scenario of the twilight at the Beach coast of Visakhapatnam a change that took place just within about 30 minutes.

Conclusions:

The most significant conclusion is that the CME and Solar flare affects on the equatorial region of Earth has been one of a considerable magnitude. The images of Sun spectra image captured by me, on the 11th August 2011 at 10h10mAM, indeed show the brilliance of the spectra. Orange filter shows the brilliant Yellow hue of the Air-Glow. On 8th August 2011 at 22h03mPM the green hue was found as dominant in spite that the blue hue persists at a low profile. Note that the reddish hue of the sky is not only due to the Sunlight refraction but also the affect of superimposed CME that has hit the Earth. The finding is that the affects continued to persist even for a few more days than the immediate impact of it like the one, as observed by Lance Taylor of Edmonton, Alberta.

The other significant finding of this investigation is that the Gray Bay of Bengal hue has gradually changed with the predominant deep blue of the Moon shine scenario of the twilight at the Beach coast of Visakhapatnam a change that took place just within about 30 minutes. I reiterate that the gray hue is due to the enhanced affect of the upper atmosphere of the earth due to the intense X-ray and possibly the Microwave and Utra-Violet irradiations.
