V1159 Ori: superoutburst

 ER UMa type dwarf nova V1159 Ori starts a superoutburst around
Nov 20. After that, we have received observations from William 
Stein and Kiyota-san. According to these data, this object is
showing superhumps with the period of 0.06423 (2) d. This superhump
period supports the previous report. However, the profile of
superhumps is a little unusual since subpeaks are prominent
despite early stage of superoutburst. Since the observations
in start of superoutburst was lacked, this may be apparent.
