ER UMa: multiple superhumps ?

 We took observations of this object on Jan 9. According
to this observation, probably ER UMa was continuously 
showing netgative superhumps . However, the profile of
them is quite unusual although the observation run is 
short due to cloud. The variations of the period of ~ 
0.01 d and the amplitude of ~ 0.1 mag were seen. This 
may be multiple superhumps or QPO.

 Further observations are encouraged!
