Dear Collaborators,

Today we will implement Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare). The target region NOAA 12975 produced an X1.3 flare at 03/30/17:21 UT and also numerous C-class flares. 12975 remains its beta- gamma-delta/D-type configuration, with slightly increasing in the sunspot area. It continues to show mixed polarities in its intimidate portion. Another major (>=M5) flare is likely in the next few days.

The position of NOAA 12975 on March 31 at 03:30 UT is:

N13W40 (603", 297")
