Solar activity has been at moderate levels for the past 24 hours. Region 1476 (N11E35) is the most complex region on the visible disk, has grown to become a Fkc/beta-gamma-delta configuration, and has an area of approximately 940 Millionths. It also produced the
Natural disasters like earthquakes and tsunamis are expected to have substantial ecological effects, but if researchers don’t have enough data about the environment before the disaster strikes, as is usually the case, it is difficult to quantify these
