CI Cam Observations

I was not able to observe this target back in October when they would have been simultaneous with other observations, but I was able to get a B,V,R,I time series on Nov. 14, after FO Aqr was too far west to observe.  Not sure if these short burst time series are very helpful, but wanted to try a new target and see what its behavior was on a short time scale.

I'm interested in Be stars, so I may return to this one to see if I can resolve any emission lines with an SA-200 in the filter wheel -- pretty low rez, but still interesting.

Clear skies,
