4827	07 Aug 2017 @ 1457	---	JSJ	"Red Dwarf Geyser" - the dominant perpetual spouter in the cluster in recent years - is back on (it was off when last noticed on 27 July 2017). Two other small spouters are also active: 1) North Dwarf Geyser; 2) small pool with 2 vents at 44° 27' 47.16" North latitude, 110° 49' 50.73" West longitude (using summer 2016 satellite photo via Google Earth). The small pool with 2 vents is my informal "West Dwarf I" and "West Dwarf J" (see photo at: http://tinyurl.com/ycrl3kko). The West Dwarf I-J pool is better characterized as very frequently spitting.
4560	27 Jul 2017 @ 1812	---	JSJ	"Red Dwarf Geyser" - the dominant perpetual spouter in the cluster in recent years - is already off - looks like it has been for a while. Two small spouters are active: 1) North Dwarf Geyser; 2) small pool with 2 vents at 44° 27' 47.16" North latitude, 110° 49' 50.73" West longitude (using summer 2016 satellite photo via Google Earth). The small pool with 2 vents is my informal "West Dwarf I" and "West Dwarf J" (see photo at: http://tinyurl.com/ycrl3kko). The Dwarf vent that disappeared between 2013 and 2015 is back (it also shows up on a summer 2016 satellite photo - I didn't see it personally last year) - vent is at approximately 44° 27' 47.34" North latitude, 110° 49' 50.52" West longitude.
