Date	Begin	Peak	Min	Class	Location	Region
	09:59	10:09	18	M2.5	N06W14	11875
	10:30	10:33	7	M3.5	S07E05	11877

All times UTC. Until June 2017 classes are NOAA's reports of the time (GOES-15 and earlier included a 0.7 scaling factor); later classes come from calibrated GOES-16/18 data, so the same flare reads about 1.4× larger. Do not compare the two periods directly.
