reported to the American Association of Variable Star Observers (AAVSO), the first observed outburst of the intermediate polar DW Cancri was detected on January 25, 2007, at magnitude V ~11.36. This represented a brightening of ~4 magnitudes from both recent measurements and long term average quiescence. The outburst was of a relatively short duration, as measured from the first detection of the outburst, showing a fading of ~2.25 magnitudes in ~27 hours, and another ~1.25 magnitudes within the next ~30 hours. Follow up photometric observations show the asynchronous rotation period of the magnetic white dwarf star of this system to be 38.6 minutes, in agreement with previous studies; a strong secondary signal of ~73.7 minutes was also noted. As to whether or not the outburst was the result of disk instabilities or caused by a mass transfer event, no conclusion could be reached.
