Dear Collaborators,
Solar activity remains at an extremely low level. The small flux region in the Southern hemisphere that developed pores has now been designated as NOAA 12796. This region is classified as a beta/C-type sunspot group and produced an A7.2 flare on 16-Jan-2021 at 10:27 UT. However, 12796 has subsequently shown signs of decay. No change in flaring activity is expected over the following 24-hour period. The Max Millennium Program continues to support the coordination of observations for the PSP 7th perihelion passage. PSP is expected to cross the Heliospheric Current Sheet (HCS) in the next 6 hours, with its magnetic-footpoint location jumping to the Southern hemisphere (and also jumping in longitude). As such, we provide the model-consensus magnetic-footpoint of PSP here for two separate times (i.e., before and after PSP crosses the HCS).
The approximate position of this region on 16-Jan-2021 at 23:00 UT is:
N32W02 , ( 29", 585" )
then, following the HCS crossing, the approximate position of this region on 17-Jan-2021 at 06:00 UT is:
S27W35 , ( 500", -383" )
NOTE: PSP is orbiting in the same direction as solar rotation, but at a faster rate.
