[vsnet-outburst 10922] OT J225749.6-082228 outburst continues

[Taichi Kato]

OT J225749.6-082228 (Itagaki transient =SDSS J225749.54-082228.7) outburst
continues.  The fading rate appears to be slower than those of SU UMa-type
dwarf novae.  What would be the nature of such a large-amplitude dwarf nova?
