How it got here

16 days of record on a day-22 fire

The record here begins at 2:20am on 25 Sep and runs to 2:04pm on 15 Oct — 492 hours, 78 readings of heat. The fire is on day 22, so the first 6 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.
