V1159 Ori: superoutburst continues

 We have received further observations from William
Stein. And Kyoto group also obtained data of this
object (observer: T Ohshima). According to these data,
this object shows almost double-peak superhumps. 
Although secondary peak profile is sharper than primary 
one, the amplitude is not so small.
 Meanwhile O-C diagram implies that stage A-B transition
occurred around Nov 23. If so, the unusual profile of
this superoubutrst had already appeared in stage A.
 Further observations are encouraged!
