If you're able to do CCD time series, observations of GR Ori would be very welcome over the next few weeks. Spectra by Terry Bohlsen and others made clear this is a CV rather than a nova, and given the amplitude it is likely to be a WZ Sge star. Given that, superhumps may start to appear in the near future. If you can get good S/N (> 20) in under 5 minutes at V=14-15, it's worth your time.
If you're using old charts for this, please update them -- both the coordinates and the sequence were updated in the past few days.
Many thanks to the observers currently following this star!
