Dear RHESSI Collaborators,
Solar activity remains at a very low level. Two new spot regions have emerged since yesterday's message, designated as NOAA 11631 and 11632. NOAA regions 11629 and 11630 have only slightly evolved in the past 24 hours, both maintaining beta/D-type sunspot group classifications from NOAA. 11631 has shown the most rapid emergence of magnetic flux and is already developing significant penumbral structure around the leading spot. B-class activity is expected in the next 24 hours, with a chance for a C-class flare if 11631 continues to emerge new flux.
The position of NOAA 11631 on 13-Dec-2012 on 12:30 UT is:
N20W15, ( 235", 346" )
