V1159 Ori : superoutburst continues

 We have received further observationsof 5 nights from 
Osaka Kyoiku Univ. team (observers: Ono-san, Noguchi-san,
Nishino-san, Furukawa-san, Sakai-san, Kawabata-san, 
Masumoto-san, Kimura-san, Ishibashi-san). And we also 
took observations of this object (observer: T. Ohshima).
According to these data, this object was at brightening
stage on Nov 18. Although it is uncertain whether this
is the brightening of superoutburst or that of the previous
normal outburst, it seems that this was the beginning of
superoutburst or its precursor considering the interval.
 Data of the newest two nights shows slightly brightening.
This may be "postcursor normal outburst", which is sometimes
seen in ER UMa.
 Further observations are encouraged!
