ER UMa: negative superhump evolving

 We have received further observations from Enrique de Miguel on
Feb 2-3. Obtained data shows that the negative superhumps have
been seen. The amplitude of negative superhumps is far larger,
reaching 0.7 mag. This amplitude is near that in shortly after
the superoutburst finished. This negative supehrumps may be clearly
excited in the quiscence... Futher observations are encouraged!
