Date	Begin	Peak	Min	Class	Location	Region
	03:01	05:15	191	M1.3	S12W01	7056
	08:35	08:41	31	M1.2	S15W08	7056

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.
