How it got here
One day of record on a day-36 fire
The record here begins at 1:00pm on 10 Sep and runs to 2:40pm on 10 Sep — 2 hours, 6 readings of heat. The fire is on day 36, so the first 35 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.
