Solar activity during the reporting week remained generally
low, with X‑ray flux staying within the low C‑class range aside from a few high‑C
and low M‑class events. Activity briefly rose to moderate levels on the first
two days: an M1.0 flare from active region 11425 on April 27, followed by three
low M‑class flares and several high C‑class flares, including C8.1, C9.0, and
C9.3, from the active region 11420 on April 28. Consequently, April 28 was the
most active day of the week, and the strongest event was an M1.5 flare from
active region 11420. This region also produced a C7.4 flare on May 1 and a C8.7
flare on May 2. No significant Earth‑directed CMEs were detected in coronagraph
observations.
The latest helioseismic far‑side map suggests that a
moderate to strong active region may rotate onto the north‑east limb around May 9.
