MM#003 Major Flare Watch

Dear RHESSI Collaborators,

Based on newly found data, it seems that the major M6.6 event at 02/18/10:11 UT had Major Flare Watch region NOAA 1158 as its source region not NOAA 1162 as it was reported yesterday. The M6.6 location is confirmed by the full-disk SDO/EVE Soft X-ray image obtained at the time of the flare. The target will switch back to NOAA 1158. Another event equal to or greater than M5 is possible before west limb passage. NOAA 1162 produced numerous C-class events and a few lower-level M-class yesterday and remains capable to produce C-class events with a slight chance of another M-class event.

The position of NOAA 1158 on February 19 at 12:30 UT is: S19W71 (Solar X = 868", Solar Y = -277")
