Welcome to KPNO

POCA Co-I Dr. Jennifer Cash and physics major Bryan Pugh accompanied Dr. Walter to Kitt Peak for three nights of observing with the Coude Feed Telescope as part of the POCA research program , studying RV Tauri and Semiregular variables.

Two nights during the run were dedicated to observing in the blue region of the spectrum, with wavelength coverage from 3700 to 5100 angstroms. The third night of the observing was in the red from 6400 to 9000 angstroms. Despite some high wind speeds that caused image jitter on the guider, the run was a success.
