</address> <pre> </pre> <p> Dear RHESSI Collaborators,
<p>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 &gt;X1
flares. Further M-class activity is likely in the next 24 hours, with a
chance for an additional &gt;X1 flare.
<p>The position of NOAA 11882 on 25-Oct-2013 at 16:00 UT is:
<p>S08E64, ( -861&quot;, -170&quot; )
