[vsnet-alert 8790] Re: Ha 0242-2802 brightened

[Daisaku NOGAMI]

Dear colleagues,

Berto reported his detection of an outburst of Ha 0242-2802,
as below.  Photometric and spectroscopic observations in
quiescence have revealed that the orbital period is 107 min
and this star show deep eclipses of ~2 mag (see Mason & Howell
2003, A&A, 403, 699; Woudt et al., 2004, MNRAS, 351, 1015;
Mason & Howell, 2005, A&A, 439, 301)!

This outburst is the first one detected to date in this
object.  Although maybe a little too faint (15.8 mag),
follow-up observations are highly encouraged!

Best regards,
Daisaku Nogami
