QHO Variable Stars Variable Stars at QHO Sorry but there will be more shortly. Variables stars often require observations on many nights over a long span of time. Professional astronomers, while requiring data on many variables, cannot afford the telescope time or effort needed to obtain this data.
Amateur astronomers can and do make the observations needed by the professionals.
Any amateur, even one without a telescope can perform needed observations of these changing stars. On the night of September 18th, Quail Hollow Observatory engaged in a simultanious observing session with the Extreme Ultra Violet Explorer satellite. The system has a 113 minute orbital period. The variation of light from this CV was clearly visible even in the unprocesssed images as they downloaded from the camera. Look for more complete information as the data is reduced.
