As many UMSF members have likely noticed the current Solar Cycle (25) is off with a bang! https://en.wikipedia.org/wiki/Solar_cycle_2...progression.png. SOHO observations https://soho.nascom.nasa.gov/spaceweather/ coupled with daily comments in Space Weather https://spaceweather.com/ provide an excellent way to follow this activity.

An interesting ‘sympathetic solar flare’ https://spaceweather.com/images2024/23jan24/doubleflare.gif (a pair of flares that occur almost simultaneously in different active regions, not by chance, but because of some physical connection) was recorded by the Solar Dynamic Observatory today (1-23-2024).
The flares erupted from two active sunspot groups (AR3559 and AR3561) shown here: https://spaceweather.com/images2024/23jan24/hmi1898.gif Two papers explaining characteristics of sympathetic solar flares and their relationship to sunspot numbers and solar cycle strength are found here: https://iopscience.iop.org/article/10.1086/340945/pdf and here: https://link.springer.com/article/10.1007/s10509-022-04145-3 |
