Solar flares are highly energetic phenomena that happen inside the sunspots. The solar magnetic cycle that works in the deep interior of the Sun creates regions that rise to the surface and appear like dark spots. | Photo Credit: Photo Courtesy CESSI From sunspots to solar storms In this image captured by LASCO C3 coronagraph, the bright plasma material coming out of the sun and propagating towards the Earth is seen. It appears their predictions are matching the observations.” He was not involved in this work.

These observations are taken at Lagrange Point L1,” he said on November 4, in a message to The Hindu.ĭipankar Banerjee, a solar physicist and Director of Aryabhata Research Institute of Observational Sciences (ARIES) based in Nainital said about the prediction, “This is quite promising. We will know whether this is the CME flux based on its evolution as it passes through. Judging by data from the NASA DSCOVR satellite, the scientists observed a steep jump in transverse magnetic fields, density and speeds of the plasma wind that are tell-tale signatures of the arrival of a coronal mass ejection shock front, according to Dibyendu Nandi of CESSI Kolkata whose team predicted the event. This prediction, which was based on models built by them and data from NASA’s observatories, seems to have come true, as people from several countries were tweeting pictures of aurorae. A solar flare that occurred on the Sun triggered a magnetic storm which scientists from Center of Excellence in Space Sciences India (CESSI), in Indian Institutes for Science Education and Research, Kolkata, had predicted will arrive at the Earth in the early hours of November 4, and they said that the magnitude of this storm would be such as to trigger spectacular displays of aurora (the coloured bands of light seen in the North and South poles) in the high-latitude and polar regions, just in time for the Deepavali celebrations in India.
