(cba:news) Fwd: YZ Cnc campaign (Joe Patterson) [2016-12-21T13:45:28Z]

Hi CBAers,

Let's get to work on this star - a natural for us.  Although Christian's 
campaign is primarily directed towards the events surrounding a 
superoutburst, we have interest at other times too.  So keep an eye on 
the developing light curve for signs of an upcoming super, but also 
obtain some long, dense nights of coverage with the usual time-series 
approach.  We'd like to track orbital phase too, not just superhumps.

BTW CN Ori is another good target for long time-series.  With its 
equatorial location, we might hope to get something like true 24-hour 
coverage.  Many years ago, we got some great light curves out of CN Ori, 
but not quite enough to finish our study.  Time to do it now.

Hi,

Gary's summary of what we're after is basically spot on. Just to add 
that what we'd ideally like to catch is the first outburst after a 
superoutburst, which requires us to identify a superoutburst more or 
less in real time. This also means we'll need to monitor for a little 
while, at least past one superoutburst and possibly longer, depending on 
whether or not we can trigger on that one.

I'd definitely encourage everybody to upload to the AAVSO in addition to 
notifying the group, since their light curve generator is an extremely 
useful tool for us to quickly see where we are.

Also, if anybody feels certain that an ongoing outburst is a super, a 
quick email to me would be great, just to make sure I don't miss it.

I will make sure to keep people up to date, i.e. I'll notify the group 
once we've triggered.

Thanks for your help!

Cheers,

Christian

Hi Martin,

Visual = the good old eyeball.  There are still a few of us left who use 
it ;-)

The main task is to monitor YZ Cnc as closely as possible, as the team 
need to know when to trigger that important TOO (they are looking for a 
Superoutburst, and we know YZ Cnc will provide one).  If you see it on 
the rise I would suggest you message this group immediately as well as 
reporting your data to the AAVSO (I guess Christian's team will look 
there first for regular updates) - whether your observation is filtered, 
unfiltered or eye-balled!  At the moment it looks like YZ Cnc is fading 
from outburst.

Good luck,

Gary

Hi Gary, just checking: Visual = unfiltered?

Thanks,
