How it got here

One day of record on a day-44 fire

The record here begins at 12:56pm on 2 Sep and runs to 2:36pm on 2 Sep — 2 hours, 3 readings of heat. The fire is on day 44, so the first 43 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.
