ER UMa : negative superhumps intermittently appearred
We have received further observations from Crimean Astrophy. Obs.
(observer: Oksana Antonyuk), Okayama Univ. of Sci., Itoh-san,
Negative superhumps reappeared on Apr 24.5. Positive superhumps are
also seen in this case. However, negative superhumps disappeared
again on as early as Apr 24.8.
Considering the last superoutburst, it is no wonder that negative
superhumps appear intermittently. Further observations are strongly
encouraged in order not to make blank as possible.
