This looks like one of ours, and it's bright enough to be studied all
the way down to quiescence. So let's fire away with gusto!
And I think it's finally time to say goodbye to V1101 Aql. The coverage
has been magnificant, and so has the star. But let's make way for the
new. The only proviso is that we should *briefly* look in on it about
1-2 months hence, to establish a maximally accurate value for the two
More later om other stars...

This is the brightest northern CV discovered by MASTER-II robotic
telescopes (the one at 12.1m in Lupus was found with MASTER-WFC in
Argentina). Time-resolved photometry is strongly encouraged!

P.S. We were actually searching for the parent body of September
Perseids which should be hiding in the Northern Milky Way now. ;-) No
comet yet, but still a nice catch!
