The SE target region produced another occulted event - M9.0 x-ray event at 10/20/18:14 UT!  If the region was located on the visible disk, it would have been an X-class event.  I made the mistake of not issuing an MFW as soon as possible following the M9.  I waited until the next day's MOTD to call the MWF. The  region was too close to the limb on the 21st to ascertain its magnetic complexity but based on its production of a large occulted event, I thought that another event =/>M5 was certain and that even an isolated X-class event was very possible in the next few days. The target region was the source of an M5 on Oct. 22 and an X1.8 event on Oct. 23 at 03:13 UT.
