1RXS J053234.9+624755 was in outburst during April 2005 when this observation was made. I found it difficult to make an observation because the magnitude was jumping all over the place. I had seen DNe flickering before but not to this extent - nearly one magnitude in 20 seconds. I decided to monitor it for as long as possible so made an estimate every 10 seconds for 24 minutes. After this time I couldn't trust my eyes as they were feeling strained so I stopped. The data was later analysed by a professional and confirmed to be real flickering within the system and not due to atmospheric seeing. Flickering in CV's is not well understood, and is probably a disc phenomenon although a school of thought suggests the mass transfer stream. Whatever the cause it's amazing to watch, especially at this sort of amplitude.

Gary that is an amazing observation, are there any theories of what drives such rapid changes in luminosity? Is it related to material hitting the accretion disk?
