[vsnet-alert 9577] Re: V455 And = HS 2331+3905

[Gianluca Masi]

Hi all,

Session closed at 4:10UT, after 10+ hours of coverage under
excellent sky conditions. The #1, 36cm-f/8 unit available at
the Virtual Telescope facility was used. The final plot is
available here:

I performed a PDM period analysis over the whole dataset
from tonight, getting an estimate of 1.37 h (+/- 0.02), a
bit longer than Porb.


Good observing while the Earth spins,
Gianluca
