Dear Collaborators,
Solar activity has decreased to a low level since the last message.
Yesterday's target region, NOAA 14499 (N05W15), produced two
low C-class flares during the period, a C1.6 and a C1.0. This region
has now reduced in magnetic complexity and is currently classified
as a beta type region. The largest event during the period was a
C1.8 flare at 18:53 UT yesterday from NOAA 14498 (N14E15, beta
-gamma/D-type). 14498 also produced another C1.1 flare during
the period. NOAA 14500 (N18E21, beta/C-type) is moving closer
to 14498, and the coronal magnetic connectivity between the two
regions is becoming stronger and more complex. Therefore, today
we will switch the target region back to NOAA 14498. If possible,
please also include 14500 in your field of view. Further C-class
activity is expected, with only a slight chance of an isolated low
M-class flare in the next 24 hours.
The position of NOAA 14498 on 1-Aug-2026 at 11:30 UT is:
N14E15 (-238", 138")
