ABSTRACT:
The sudden change of weather on 2nd January 2011 evening with the descent of dense fog reducing the visibility by 40% is a consequence of the chilly winds that have blown from the North to the South in India. Certain gravity waves, doggy sun visions and the cluster formations of the clouds were very fascinating since the entire city has been engulfed in a dense fog. Sun spectrum intensity profiles at the Sun rise later during the eclipse period of 12h10m11s to 16h30m54s have been obtained. The Sun spectra with the X-Ray film filter and directly of the Sun could be obtained in spite of the possible damage to the pixel digital camera sensitivity. The mornings in Visakhapatnam are a great hindrance to observe the Sun rise in its purity and totality. The harbor environmental pollution also adds to the smog and the fog of the winter season.
Keywords: Gravity waves, Sun visible spectra, Cloud formations, fog.
INTRODUCTION
The chilly and snow weather engulfed the North India extreme regions of Jammu & Kashmir valleys and the Himalayan range. The weather in USA and Europe was also very snowy, blocking the several roads, pathways and cold. On 2nd January 2011, Araku Valley near Visakhapatnam and New Delhi are equally dense with fog. In New Delhi temperature maximum was only 14.6degC which is about 6degC less than the expected temperature. Leh recorded -23degC and Gulmarg, Southern Kashmir Pahalgaon, recorded less than -12degC. Bajigunda patanam has recorded -7.4degC. Anantha Nag and Kokarnag have recorded -6degC. On Sunday 2nd January 2011 Srinagar recorded -2.4degC. There were chilly winds that caused some deaths. The first snow fall in Jammu & Kashmir was on 30th December 2010.
Partial Solar Eclipse:
The occurrence of partial Solar Eclipse over the North India, North Europe North Africa and West Asia and the Islands of the Arabian Sea on the Tuesday 2011 for about four noon hours has affected the onset of weather changes considerably. On the mid afternoon of the 5th January 2011 the chilly weather suddenly took over Visakhapatnam that continued to the afternoon of 6th January 2011.In Europe morning partial eclipse was only barely visible.

1. INDIA NEWS ECLIPSE
In Delhi, the eclipse started at about 3.12 p.m., with the peak being at 3.32 p.m. hours and ended at 3.52 p.m. The maximum portion of the Sun covered during the eclipse was only three per cent, Science Popularisation Association of Communicators and Educators (SPACE) General Secretary Sachin Bhambha said.In India, the eastern fringe of the penumbral shadow of the Moon passed over the Kutch and other parts of Gujarat, Rajasthan, Haryana, Uttar Pradesh, Delhi, Punjab, Uttarakhand, Himachal Pradesh and Jammu and Kashmir, retired Prof. R. C. Kapoor of Indian Institute of Astro Physics said. The next best opportunity to see a solar eclipse covering major parts of the country will be on December 26, 2019. In 2011, a total of six solar eclipses will occur — four solar and two lunar. N. Raghunandan Kumar of Planetary Society of India said a combination of four solar and two lunar eclipses in a single year will occur only six times during the 21st century — 2011, 2029, 2047, 2065, 2076 and 2094. The Eclipse is happening in the Purvashadha Nakshatra of Dhanu Rashi hence Ganesha advises the people of Dhanu rashi and purvashadha nakshatra to remain alert for health issues.

Sweden, saw the maximum eclipse, with about 80 percent coverage. The morning skies over Europe, the Mideast and elsewhere dimmed in an unnatural twilight early Tuesday when the moon blocked part of the sun in the first partial solar eclipse of the year. In Rome, cloudy skies made the solar eclipse a touch eerie as the moon appeared to take a bite out of the sun during the three-hour eclipse. "It was a memorable experience, and I feel lucky to [have seen] it," said astronomer Gianluca Masi of Italy, who observed the event as part of the Virtual Telescope Project. Masi watched the partial solar eclipse from Rome, where the sun was just under two-thirds — about 61 percent — obscured by the moon. In Sweden, where the eclipse was at its maximum, the moon blocked out about 80 percent of the sun's disk. Skywatcher Dennis Put of Maasvlakte in the Netherlands snapped stunning photos of the solar eclipse at sunrise, despite a disheartening weather forecast. "The expectations on viewing the eclipse the day before were not very high due to a great chance on complete cloud overcast, but it turned out well!" Put said in a description of the event. Put's photos show the solar eclipse already under way as the sun was rising, giving the dawn what he described as a "double sunrise" look. At one point, an airplane passed across the face of the sun, offering a double eclipse of sorts. There were still some clouds that in the sky over the Netherlands, but Put said they didn't intrude too much. In all, Put took 675 photos of the partial solar eclipse. "A successful eclipse!" he exclaimed. Likewise, Masi said the eclipse still dazzled, despite a cloudy sky above Rome. "The clouds added some special flavor the images," Masi told Space.com in an e-mail. Masi said the sun was low on Rome's southeastern horizon during the eclipse. Tuesday's partial solar eclipse began over Algeria. According to Sky & Telescope magazine, millions of skywatchers across Europe and parts of Africa, the Middle East and Asia had a chance to observe the eclipse, weather permitting. "Europeans won't get another opportunity to see the sun covered to this extent until March 20, 2015," Sky & Telescope reported before the event.

The geomagnetic field is expected to be at quiet levels during day 1 (05 January) of the forecast period. Activity is expected to increase to quiet to unsettled levels on days 2 and 3 (06 - 07 January) as a recurrent coronal hole high speed stream begins to disturb the field.
4. ASTRONOMY:
To start the day off we have Mercury shining brightly in the east-southeastern sky about an hour before the sun comes up. Then, you can find Venus, also shining bright, far to the upper right of Mercury. Saturn rises at about 1:00 am ET, but it becomes best to view during dawn as well. Find it to the far upper right of Venus in the south-southeast. Mars remains hidden in the glow of the sunset for now. The Winter Triangle is now seen up in the east-southeast at around 8:00 pm ET. It is made up of Orion's star Betelgeuse, the star Procyon to the left and brilliant Sirius on the bottom. It is actually nicer and brighter than its counterpart, The Summer Triangle, appearing more colorful and even more equilateral. Vega can be spotted low in the northwestern sky after it gets dark and Deneb, which is the head of the Northern Cross, is seen right above it.

"We were dumbfounded," said Roger Blandford, who directs the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University. The Crab Nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with a propensity for fireworks -- gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object.
