Observations, Jul 30, 2014
(JD 2456868)
DQ Her

This is a time series observation of a 15th magnitude CV in the constellation Hercules. The CV is the primary star (.6SM), orbiting a red dwarf (.4SM) secondary star.  The orbital ellipse is steeply inclined in relation to Earth. These factors result in a very steep eclipse light curve. The lightcure graph showes the DSF data (Red) supperimposed over AAVSO data (Blue) two periods (09.5 hrs) earlier. DQ Her underwent a dwarf nova in  1934 and a planitary nebular is visible aroung it.
