How it got here

Two days of record on a day-55 fire

The record here begins at 2:38pm on 22 Aug and runs to 3:38am on 23 Aug — 13 hours, 26 readings of heat. The fire is on day 55, so the first 53 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. There is no long arc to draw yet. What follows is what has actually happened.
