No satellite heat has been attributed to this fire yet — either it is too new for a pass to have caught it, or it is too small to register from orbit. Everything above is from the interagency incident record and updates as that record does.
Each step is a change on the interagency incident record — acreage, containment or crews — with the date it was reported. No satellite reading is involved.
