[vsnet-alert 3968] RX J0640-24 possible superhump?

RX J0640-24 possible superhump?

Dear Colleagues,

    From a 1.3-hour continuous run (vsnet-alert 3959), we have detected
a modulation with an amplitude of ~0.3 mag, which might be attributed to
a superhump.  However, the large air-mass may be responsible.  Longer
observations at other longitudes (contributions from the southern hemisphere
are extremely welcomed!) are strongly encouarged to clarify the nature
of the object.  Collaborating observations should be sent (as usual)
to uemura@kusastro.kyoto-u.ac.jp.

    Weather permitting, we will try to make a longer run tonight.

Regards,
Makoto Uemura and Taichi Kato
