Time-resolved photometry of the eclipsing polar CSS 081231:071126+44040 was obtained with the Vatican Advanced Technology Telescope (VATT) on four nights in October 2009. The light curve shows a single accretion hotspot lagging 10 degrees behind the secondary. The last two nights of data show "sputtering" accretion and the hotspot nearly disappears in consecutive orbits.
