Date	Begin	Peak	Min	Class	Location	Region
	06:17	06:22	12	M1.0	S35W80	5273
	15:55	15:59	17	M1.0	S31W69	5275

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.
