[vsnet-alert 78] AK Cnc superhumps and cooperation

[rmennick@buho.dpi.udec.cl (Ronald Mennickent Cid)]

Dear Collegues:

               I have observed 2 superhumps maxima in March
12, UT= 03:47 and 05:14, during the current supereruption of
AK CnC. The first superhump is broad and the second one is narrow.
Both have amplitude approx. 0.2 mag. in the V band. The broader
superhump is characterized by a slow increase and a rapid decline of
luminosity. I pretend to continue monitoring this star with thr
1.0 m telescope at Las Campanas Observatory, Chile, with different
bandpasses during the next 4 nights, if weather continues good.

We plann to observe AK Cnc spectroscopically during March 20-24
from Beijing and Las Campanas (Mr. Xue-Bing WU has kindly offered
to collaborate in a joint, coordinated campaign).

If you are interested in cooperate with photometric or spectroscopic
observations please contact with me at:

Thank you in advance !
