To begin, my apologies for taking so long to post this-just wanted to be sure it happened.
From data obtained via tempmeter, Fan and Mortar erupted on January 09, either at 1350 or 1450 (we are unsure if the time was MST or MDT). This was a full major eruption. A few days before the eruptions, the "River Vent" cycles were running about 120 minutes apart.
The week before, Spiteful had been active, but it had stopped by Jan 04.
Norris Pool did have a couple of small eruptions after F&M.
"Arch/Bottom" Vent and Lower Mortar were having minor eruptions in late December, late January, and late February to present. The intervals are about two days apart.
