How it got here

Seven days of record on a day-37 fire

The record here begins at 2:54am on 22 Aug and runs to 3:00am on 28 Aug — 144 hours, 135 readings of heat. The fire is on day 37, so the first 30 days are missing: nothing showed up from above until the fire was large enough and the sky over it clear enough for it to be seen.
