ER UMa: negative and positive superhumps
 
 We have received further observations from Enrique 
de Miguel. This superoutburst of ER UMa had lasted
for 10 days. Thus it is interesting when the abrupt
decline will occur (In this object, when the negative
superoutburst were seen, the length of superoutburst 
may be a little shorter). Negative superhumps were
seen. However, positive superhumps seem to remain
intermittently.

 Further observations are encouraged!
