Since past one week there is much news about solar flares. A
flare is defined as a sudden, rapid, and intense variation in brightness. A
solar flare occurs when magnetic energy that has built up in the solar
atmosphere is suddenly released. The amount of energy released is the
equivalent of millions of 100-megaton hydrogen bombs exploding at the same
time! It is reported that even yesterday two new solar flares erupted, blasting
streams of plasma and charged particles into space. The picture at the top of
this article shows an active region on Sun, seen as the bright spot to the
right. This spot, designated as AR 1429 has in the past couple of days produced
three X-class flares and numerous M-class flares. Space weather scientists use
five categories to rank solar flares – A, B, C, M and X, based on their
strength and severity. A-class flares are the weakest types of sun storms,
while X-class flares are the most powerful eruptions.
The precise and total affects of much stronger solar flares is
not clearly known, however there is theoretical and practical proof of it
affecting all forms of electronic communication with a severe threat to all
space satellites and telecommunications. Long term affects are not precisely
known but scientists suspect highly disturbed weather patterns and an increase
in risk of earthquakes or volcanic eruptions at vulnerable locations. Some
scientists also predict intense medical and emotional consequences.
A solar tsunami; a giant explosion of energy from the Sun is predicted in 2013 or
in the months following it, which could paralyze earth. All this information and
predictions are very scary.
