ER UMa: normal outburst and negative superhump

 We have received further observations from Enrique de Miguel, 
Osaka-Kyoiku Univ. team, Itoh-san, Shiokawa-san. According to
these data, this object underwent a new normal outburst on Feb. 5.
Although this object underwent the last normal outburst Jan. 29,
The variations like negative superhumps are seen in the brightening
phase in the present outburst while variations are not clear in
the brightening phase in the last normal outburst. Further
observations are required since the future behavior of this object
cannot be predicted now!
