Dear Collaborators,

Solar activity has been at a moderate level since the last message, with an increasing trend in the recent 12 hours. The largest event in the past 24 hours was an M1.4 flare at 15:11 UT today (11/3) from the Northern portion of NOAA 13869 but the intensity has a contribution from the C8.2 flare from NOAA 13883 occurred right before(14:27 UT).

The target region NOAA 13878 produced an M1.2 flare at 8:39 UT today in addition to two mid-C class flares. The positive polarity patch located at the Northeast of the trailing spot, formed a separate sunspot after the M1.2 flare. However, this region forms clear sigmoidal loop structures observed in the EUV high temperature range and soft X-ray wavelengths. We will continue the Major Flare Watch with NOAA 13878 for another 24 hours. We will observe the center of the sigmoid, the Southwest side of the trailing spot, expecting another low M-class event or larger.

The position of the target in NOAA 13878 on 3-November-2024 at 17:30 UT is: N15W09 (156", 193").
