ER UMa: superoutburst continues

 We have received further observations from Akazawa-
san and William Stein. According to these data, this
object is undergoing a superoutburst. Positive superhumps
was seen in the earlier stage. However, positive 
superhumps weakened on Jan 6 and negative superhumps
exceeded instead. Since the beat phenomenon was seen
also on Jan 5, negative superhumps seemed to appear
before the negative superhumps got clearer than positive
superhumps.
 Further observations are encouraged!
