Date	Begin	Peak	Min	Class	Location	Region
	02:15	02:42	53	M3.4	S14W61	12192
	13:54	14:06	29	M1.6	S18W73	12192

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.
