ABSTRACT:
An observation of the unusala Solar Spectrum has been made at Visakhaptnam beach coast hat showed Day time Aurora Display of the direct impact of the CME that has reached even the south polar terrestrail region. The present observation is not a hue of color but a yellow region dominant spectral preponderance of the Solar Shine. Essentially a Yellow Plasma ball shower that engulfed the equatorial region has occurred. This is the first time that such a finding has been made. The spectrums found are really fascinating and astounding. A glancing blow to our magnetic field on August 9th and 10th has definitely affected the equatorial region of the earth. It’s but necessary to state that the Plasma Ball event of nearly several hours observed by me is far significant than the aurora productions in the polar regions of the Earth’s magnetosphere.
OBSERVATIONS MADE:
Figure given below gives all the images obtained using the IXUS Canon 14.2MP digital camera.
On August 7th (1825 UT), magnetic fields around sunspot 1093 became unstable and erupted, producing a strong M1-class solar flare. The eruption hurled a coronal mass ejection (CME) into space, just missing a direct sun-Earth line. Forecasters expect the cloud to deliver no more than a glancing blow to our planet's magnetic field when it billows by on August 9th or 10th--not be a major space weather event. The flare produced intense radio bursts detectable by ordinary shortwave receivers on Earth. In New Mexico, amateur radio astronomer Thomas Ashcraft picked up strong emissions around 21 MHz. At 1825 UT on August 7th, Earth-orbiting satellites detected a long-duration M1-class solar flare. The source of the blast was sunspot 1093. A glancing blow to our magnetic field on August 9th or 10th might produce auroras, but this does not appear to herald a major space weather event at Earth.
Active sunspots 1092 and 1093 are both large enough to see without the aid of a solar telescope on the 7th August 2010. Sunspot 1093 has splitting in two eventually like Pass the cigar, according to the photographer Alan Friedman, "it's twins!" The spaceweather.com has nicely projected the images and the scenario of Aurora Australis.” Hrubes is wintering over at the Amundsen-Scott Station where he oversees operations of the South Pole Telescope (SPoT), silhouetted above by aurora australis. "After one of the windiest Julys on record, we finally got some very clear skies on August 9th," he says. "The auroras were a welcome surprise. The sun will be returning to the South Pole in a little over 6 weeks, so I'm hoping for more auroras soon."
My observation has remarkably shown the positive role of the yellow spectral region of the visible spectrum recorded over a period of more than 9hours at Visakhapatnam ranging from morning 8hours to around 15h26m on the 9th August 2010.
Essentially a Yellow Plasma ball shower that engulfed the equatorial region has occurred. This is the first time that such a finding has been made. The spectrums found are really fascinating and astounding. Previously the present author has observed a Golden hue of color mentioned even in Vedic times of India that the solar eclipse has produced that lasted only few minutes around the peak period of the partial solar eclipse observed in the afternoon time at Visakhapatnam. The present observation is not a hue of color but a yellow region dominant spectral preponderance of the Solar Shine.
The top left & bottom images of the Sun Yellow dominant spectrum of the 9th August 2010 at 11h10m and at 11h15m are really surprising. And so the author continued the observation in the day time in spite of the cloudy weather and obtained the solar spectrum that was split by the passing clouds and the phenomenal yellow dominant spectral radiation has been detected. Even at 15h26m the yellow dominant spectrum has been detected.
It was thought that the impact of the lopsided CME probably won't trigger a major geomagnetic storm---but the SOHO data show it could be bigger than expected. High latitude sky watchers should be alert for auroras when the cloud arrives probably on August 10th. Could it be that the already simmering sky of the sky even in the south polar region on the 9th August 2010 was a direct evidence of the CME affects? On August 10th, 2010 also there were no coronal holes on the surface of the Sun.
CONCLUSIONS:
The present observation is not a hue of color but a yellow region dominant spectral preponderance of the Solar Shine. Essentially a Yellow Plasma ball shower that engulfed the equatorial region has occurred. The coronal mass ejections either have penetrated the equatorial belt or at least have an important component of neutral plasma that generated plasma collisions of the unusual kind. This is the first time that such a finding has been made. The spectrums found are really fascinating and astounding. A glancing blow to our magnetic field on August 9th and 10th has definitely affected the equatorial region of the earth. It’s but necessary to state that the Plasma Ball event of nearly several hours observed by me is far significant than the aurora productions in the polar regions of the Earth’s magnetosphere. The astronomy observations made by me in the third week of July 2010 would be soon replaced by me at this blog spot posts following the sky maps available with SpaceWeather.com of the Planets Venus etc.
ACKNOWELDGMENT:
I am deeply indebted to late Professor K.Rangadhama Rao D.Sc.(Madras) .D.Sc.(London) who encouraged to observe and photograph the sky. My first observation was that of a Comet during the 1960s from the terrace of Narasimha Ashram,official Colony, Maharanipeta.P.O . I have used at that time a Nikon F camera gifted to me by Dr.K.V.N.Rao of Bedford,Mass., USA. That first gave me a glimpse of the Plasma Phenomenon that would visibly occur in the Terrestrial Sky even during the day time.
