Solar activity continued to decline as the current solar cycle progressed through its declining phase. Activity levels remained low throughout most of the reporting period, with the exception of October 19, when Active Region 14551, located in the southwestern quadrant of the solar disk, produced an M1.6 flare, temporarily elevating activity to moderate levels. This was the strongest event recorded during the week. Several low-intensity C-class flares were also observed throughout the reporting period. By the end of the week, nearly all numbered active regions had rotated onto the far side of the Sun, leaving the Earth-facing disk largely devoid of significant activity. The attached figure displays three sample images obtained at the Big Bear GONG site on October 25, toward the end of the reporting week. No Earth-directed coronal mass ejections (CMEs) were detected during this period.
Analysis of recent far-side helioseismic maps suggests the
emergence of a new moderate-sized active region in the northern hemisphere.
Based on its current location, the region is expected to rotate onto the
visible solar disk around October 30.
