Here is my 3-Hour timelapse video of AR3576 a complex and highly active magnetic storm just now appearing on the surface of the sun and a single frame of one of the larger flares. Imaged from Batavia Ohio. I also have footage of AR3575 I hope to post tomorrow after work.
AR3575 and AR3576 have been very active - showed strong flaring potential, in part due to their magnetic complexity. And AR3576 then went on to produce 10 of the past day’s 11 M flares, and 19 of a total of 25 flares in the past 24 hours.
AR3576 is a whopping 4.5 times as big as Earth.
From SpaceWeather's web site:
Last 24 hours: Eleven M flares bring sun activity to high. Ten came from AR3576 and one from AR3575. The total flare production was 25 between 11 UTC yesterday and 11 UTC today. The largest event was an M2.7 from AR3576 at 22:34 UTC on February 4. The full list of M flares is:
M1.4 at 11:40 on Feb 4 (AR3576)
M1.5 at 16:22 on Feb 4 (AR3576)
M1.3 at 17:05 on Feb 4 (AR3576)
M1.1 at 18:16 on Feb 4 (AR3575)
M1.3 at 20:52 on Feb 4 (AR3576)
M2.1 at 22:20 on Feb 4 (AR3576)
M2.7 at 22:34 on Feb 4 (AR3576)
M1.8 at 22:45 on Feb 4 (AR3576)
M2.2 at 04:13 on Feb 5 (AR3576)
M1.5 at 04:36 on Feb 5 (AR3576)
M1.5 at 06:26 on Feb 5 (AR3576)
All of these flares caused R1 (minor) radio blackouts over the sun-facing side of Earth as each flare occurred, centered where the sun was highest in the sky at the time of the flare.
AR3575 has decreased somewhat in size to about 1 1/2 times the area of Earth. AR3576 is much larger at 4 1/2 times the area of Earth. Both AR3575 and AR3576 have high magnetic complexity with delta regions. AR3575 is more complex with a beta-gamma-delta configuration. AR3576 is gamma-delta but its flare output indicates that it may be more complex. Because it has not fully rotated into view, an accurate magnetic complexity determination is more difficult. Over time the probability of flaring has increased. Stay tuned to see if these regions bring us more excitement.
Next 24 hours: The forecast is a 99% chance for C flares, a 75% chance for M flares, and a 25% chance for X flares!
