(cba:news) Fwd: Re: (cba:chat) MAXIE J1820+070 paper (Joe Patterson) [2019-08-10T20:14:20Z]

Hi CBAers,

Joe and Josch are at it again... and Maxie is at it again, at least to 
some degree.  That means it's back to the sky's highest priority.  
Seasonally appropriate for long runs, and dec-appropriate for all 
observers (who can handle 16.6).  HIgh time resolution not needed; 60-90 
s is just fine.

See if you nail it tonight and report quickly; it would be good to get 
the X-ray telescopes going if this is sustained. (Though they may 
already be observing it, since they all fell in love with this star last 
year.)

I can confirm that I also measured Maxie at mag 16.658 (V band) last 
night, which is about 1.5 magnitudes brighter than normal lately.

   Joe,

   I may have access to a larger telescope, though I do not yet know
   for how long.
   Would it make sense to go for time series for MAXIE?
   I have observed it last night at mag 16.8 (V band) and based on the
   AAVSO data there seems to be a tendency of an increase from the dip
   around mag 18.5 a few nights ago (around begin of August).

   Absolutely!  The one thing holding us up was the knowledge of Porb
   (which reveals q through the venerable epsilon (q) relation.  Time
   to finish it now
