Dear Collaborators,
Solar activity has slightly decreased since the last message. The largest event was a C3.0 flare at 15:46 UT yesterday, attributed to NOAA 14045 (S13W64, beta/B-type). However, an occulted flare from the limb region NOAA 14043 also contributed to the soft X‑ray flux. The target region NOAA 14048 (S16W32) produced three low C‑class flares in the period, the largest being a C2.7 at 06:41 UT today. NOAA 14048 retains a beta‑ gamma configuration, with magnetic flux emergence in its trailing portion. Today, NOAA 14048 remains the target. Additionally, NOAA 14054 (S12W07), mentioned in yesterday's message, produced a C2.0 flare during the period. This region has developed into a beta‑gamma configuration and is undergoing significant magnetic flux emergence in its intermediate portion. Further C‑class activity is expected, with the possibility of low M‑class flares in the next 24 hours.
The position of NOAA 14048 on 7-Apr-2025 at 07:30 UT is:
S16W32 (489",-179")
