I observed ASAS 002511+1217.2 for about 6 hours tonight. The star is bright, about V=11.1. Light curve shows nice superhumps with an amplitude of 0.2 mag. Period analysis with Peranso/ANOVA gives period of 0.0569 days. 

Pretty good conditions, but some clouds in the middle of the run. Not very good seeing, about 4 arc seconds.

Equipment: 40 cm Meade LX200 + SBIG ST8XE + V-filter. Exposure time 20/30 seconds.
