FLAMINGOS-2 on Gemini South

FLAMINGOS-2 is back on sky after work to repair the dekker wheel. Queue observations of imaging programs have been resumed, guided with the telescope peripheral wave front sensor. For the moment, the K-band internal background is higher than normal, because the gate valve baffle is not positioning properly. Until additional work is scheduled, spectroscopy observations will continue but be limited to shorter wavelengths (using the JH and R3000 grisms, in the JH, Y, J, and H bands).
