Smoke has been recorded lying over this ground two times so far. The thickest of it was thin between 1:10pm and 4:30pm local time. The last of those windows closed 185 hours ago, so what is overhead now is not known.

How it got here

Six days of record on a day-43 fire

The record here begins at 2:55pm on 3 Sep and runs to 2:56am on 8 Sep — 108 hours, 45 readings of heat. The fire is on day 43, so the first 37 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.
