Dear Collaborators,
Solar activity has been still at a mid-B level. The target region has been numbered as NOAA 13628 and classified as an alpha/H-type sunspot group. Although 13628 only produced a B4.1 flare at 01:09 UT today, it is experiencing an emergence of new magnetic fluxes. Note that a spotless region (S22W87) was a source of three >B5 flares and NOAA 13626 (N13W71, beta/B-type) produced three low-B flares. These two regions are very close to the west limb, so NOAA 13628 will remain the default target. More B-class activities are expected, with low C-class flares possible from various regions in the next 24 hours. The position of NOAA 13628 on 4-Apr-2024 at 15:30 UT is: N07E58 (-808", 172") See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
