2377 18 Sep 2015 @ 1135 --- MAB Filled and flooded the crater area, with a few blips. I have not seen that for a while. It was promising enough that I recorded it, expecting it to continue to eruption, but that's all it did.
1784 22 Jun 2015 @ 2003 --- MAB Returning from the Congress area I saw it IE, would have called it a near start last year, or even near-end; it was full and splashing to 6-8". This however was the extent of the eruption.
