Fermi ToO 060602-1-1

A ToO observation to observe SUN at RA, Dec = 210.2790, -17.3300 (J2000) was approved at 2013-10-25 19:02:55 UTC.

The justification for the ToO is: From the Max Millennium Chief Observer: 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 planned duration is 250.00 ks.

The autonomous request threshold during this ToO is OFF.

The ToO observation should begin between 2013-10-25 19:02:55 UTC and 2013-11-01 19:02:55 UTC.

The ToO observation was requested by DR. JON ERIC GROVE.

The ToO commanding order was sent to the MOC at 2013-10-25 19:21:57 UTC.

The MOC acknowledged receipt of this order at 2013-10-25 19:23:43 UTC.

The MOC sent the ToO execution notification at 2013-10-25 19:37:38 UTC.

The ToO order status is Uplinked at or before: 2013-10-25 19:36:18 UT
