MM#003 Major Flare Watch
by Max Millennium Chief Observer 31 Oct '24

31 Oct '24

Dear Collaborators, Solar activity has significantly increased since the M7.2 event yesterday(10/30). After this event, NOAA 13878 produced 3 low-M class (M1.0 at 2:16 UT, another M1.0 at 3:23 UT and M1.4 at 9:22 UT all on 10/31) as well as a few high-C class flares. Other notable events are an M2.4 flare from NOAA 13875 at 12:41 UT and an M1.2 flare from NOAA 13876 at 13:46 UT today. We will continue to observe NOAA 13878 as the target of the Major Flare Watch campaign. The magnetic configuration of this region was updated to a beta-gamma-delta type. We will observe the area of delta configuration (west side of the trailing sunspot) for the next 24 to 48 hours, expecting additional M class flares and larger. The position of the target in NOAA 13878 on 31-October-2024 at 16:30 UT is: N15E30 (-474", 197").

Dear Collaborators, NOAA 13878 has produced an M7.2 flare at 20:29 UT today (10/30). At this time, we will implement the Major Flare Watch campaign with NOAA 13878. We will observe the small positive polarity area located in the west side of the trailing (negative polarity) sunspot. The position of the target in NOAA 13878 on 30-October-2024 at 22:00 UT is: N15E40 (-606", 204").

MM#009 Default Target
by Max Millennium Chief Observer 30 Oct '24

30 Oct '24

Dear Collaborators, Solar activity has declined to a low level since the last message. The largest event in the past 24 hours was an M1.1 flare at 16:21 UT on 10/29 from NOAA 13873. The target region NOAA 13878 has got quiet down since yesterday with no flare activity reported in the past 24 hours. NOAA 13876 located in the Southwest quadrant has undergone new flux emergence at the location of its trailing sunspots, and so far produced 3 C class flares with the largest being a C7.1 flare at 9:10 UT today(10/30). The newly appeared sunspots increases magnetic complexity of this region to be classified as a beta-gamma-delta type. We will switch the default target to NOAA 13876, and observe the area of newly appeared sunspots for the next 24 hours. Additional C class to low-M class flares are expected. The position of the target in NOAA 13876 on 30-October-2024 at 16:00 UT is: S05W26 (431",-154").

MM#009 Default Target
by Max Millennium Chief Observer 29 Oct '24

29 Oct '24

Dear Collaborators, Solar activity has been at a moderate level since the last message. The target region NOAA 13878 continues to be the main source of the flare activity in the past 24 hours. NOAA 13878, being classified as a beta-gamma type (E-type), produced an M4.2 flare at 16:13 UT on 10/28 and more than 10 mid-to-high C class flares from its trailing sunspot. It is worthy to note that currently there are 3 active regions (NOAA 13869, 13872 and 13874) classified as a beta-gamma-delta type, but they have not been showing much activity compared to NOAA 13878 in the past 24 hours. We will continue to observe the trailing spot of NOAA 13878 for the next 24 hours, expecting additional C class events and larger. The position of the target in NOAA 13878 on 29-October-2024 at 15:00 UT is: N15E58 (-793", 219").

MM#009 Default Target

28 Oct '24

Dear Collaborators, Solar activity has maintained a moderate level since the last message. The target region NOAA 13873 reduced both in size and magnetic complexity. Only flare event reported from the active region group (consisting of NOAA 13869, 13872 and 13873) in the past 24 hours was a C3.8 at 6:11 UT today (10/28) from NOAA 13869. At this time, we will end the Major Flare Watch campaign with this active region group. The major source of flare activity was from the Northeast limb region, now designated as NOAA 13878, which produced 3 M class flares on 10/26. This region produced another 2 M class flares (M2.9 at 23:05 UT on 10/27 and M1.3 at 3:59 UT on 10/28) as well as several mid-to-high C class flares during the past 24 hours from its following (negative polarity) sunspot. We will observe the following sunspot of NOAA 13878 as a default target for the next 24 hours. Additional C to M class events are expected, with a slight chance of a major (>M5) flare. The position of the target in NOAA 13878 on 28-October-2024 at 15:30 UT is: N14E70 (-878",218").

MM#003 Major Flare Watch

27 Oct '24

Dear Collaborators, Solar activity has been at a moderate level since the X1.9 event yesterday from NOAA 13873. The largest event in the past 24 hours was an M2.9 flare at 11:57 UT yesterday (10/26) from an unnumbered region on the Northeast limb. This region produced two more M class flares and a few high-C class flares during the long decay phase of the X flare. The target region, NOAA 13873 only produced a high C class flare at 18:04 UT on 10/26, but increased magnetic complexity to a beta-gamma type. We will continue the Major Flare Watch campaign for another 24 hours with NOAA 138773, in the Southeast area of mixed polarities. An isolated M class flare or larger is expected. The position of the target in NOAA 13873 on 27-October-2024 at 15:30 UT is: S12E41 (-629",-259").

26 Oct '24

Dear Collaborators, Solar activity has increased to a high level since the last message. NOAA 13873 located at the Eastern most of the active region group (made of NOAAs 13869, 13872 and 13873) produced an X1.9 flare at 06:32 UT today(10/26) following an M9.5 event at 05:58 UT associated with a filament eruption from the South side of this region. NOAA 13863 is the smallest (120 millionths) and classified as a beta type, but has repeated eruptions observed in EUV wavelengths during the past 24 hours. We will continue the Major Flare Watch campaign with the target shifted to the South side of NOAA 13873. Additional M class flares or larger are expected in the next 24-48 hours. The position of the target in NOAA 13873 on 26-October-2024 at 15:30 UT is: S12E54 (-771",-253").

25 Oct '24

Dear Collaborators, Solar activity has been at a moderate level after the X3.3 flare yesterday. Out of two bipolars mentioned in yesterday's message, the one on the east was given a new number, NOAA 13872. There is another bipolar region located in the Northeast of the two and designated as NOAA 13873, which produced an M1.2 flare at 07:23 UT today(10/25). These regions are still close to the limb and hard to determine the magnetic connectivity, or pairing of the sunspots. Active regions NOAA 13869, 13872 and 13873 constitute an active region group with complex magnetic configuration and has been a source of large flares in the past 24-48 hours and will continue to be so for the next 24-48 hours. In the next 24 hours, we will continue the Major Flare Watch on the center area of this active region group (NOAA 13872) where new flux emergence is observed. Additional M class events are expected with the chance of a major (>M5) flare. The position of the target in NOAA 13872 on 25-October-2024 at 16:30 UT is: S18E60 (-795",-340").

24 Oct '24

Dear Collaborators, Solar activity has increased to a moderate-to-high level since the last message. The target region, now designated as NOAA 13869, has produced an X3.3 flare at 03:30 UT today(10/24) followed by an M1.2 flare at 10:22 UT and a C6.4 at 12:42 UT. At this time, we will implement a Major Flare Watch campaign on NOAA 13969. NOAA 13969 consists of at least two pairs of bipolar sunspots and the X3.3 flare was initiated by a filament eruption located at the center area of the two bipolar system. We will observe the area between the two bipolars for the next 24 to 48 hours, expecting additional major flares larger than M5. The position of the target in NOAA 13869 on 24-October-2024 at 15:00 UT is: S18E66 (-841",-333").

MM#009 Default Target

23 Oct '24

Dear Collaborators, Solar activity has been at a low-to-moderate level since the last message. The largest event in the past 24 hours was a C7.9 flare at 11:37 UT today(10/23) from NOAA 13863. Yesterday's target now rotated from the Southeast limb appears to be a bi-polar spot, but is yet to have a NOAA number. This region produced a few mid-C class flares including a C5.1 at 00:07 UT today(10/23), and is showing frequent eruptive features observed in the EUV 304A. We will continue to observe this region (center of 2 sunspots) for the next 24 hours. Additional C class flares or larger are expected. The position of the target on 23-October-2024 at 15:30 UT is: S16E71 (-878",-301").
