[vsnet-alert 8897] Re: CTCV J0549-4921 in outburst

[Akira Imada]

Dear Colleagues,

I've just checked the ASAS-3. The previous eruption of 
CTCV J0549-4921 was recorded in 2004 January (duration as long as 2weeks).

Quiescent studies were performed by Tappert et al.(MNRAS, 354, 321, 2004) 
in which the period of the system was 0.080 days. Optical spectrum also
indicates the dwarf nova nature of the object.

CTCV J0549-4921 is a possible candidate for UGSU stars.
High speed photometry is encouraged.

Regards,
Akira Imada
