Dear RHESSI Collaborators,

Solar activity is at a high level. NOAA region 11882 has recently rotated onto the visible disk over the South East limb, but has already produced 2 X-class flares in the past 7 hours (an X1.7 and an X2.1 on 25-Oct-2013 at 07:53 UT and 14:51 UT, respectively). This region is classified as a beta/D-type sunspot group by NOAA, but its proximity to the limb limits the accuracy of a magnetic designation. At this time we are initiating a MM#018 Great Flare Watch, due to NOAA 11882 having produced multiple >X1 flares. Further M-class activity is likely in the next 24 hours, with a chance for an additional >X1 flare.

The position of NOAA 11882 on 25-Oct-2013 at 16:00 UT is:

S08E64, ( -861", -170" )
