[Aavso-photometry] The shutters are open and HMXB campaign will be underway in 1 hour! Yippee!

[Richard Huziak]

OK AAVSOvians! 

The scope is cooling to ambient with the dome shutters open now in the 
1.85m DAO scope in Victoria BC, Canada.  Clear, clear, clear!

I got work for ever last one of you tonite!  How about giving me some 
coverage on the HMXB campaign stars? 

The job is easy!  Set up on an HMXB star and run on it as long as you 
can tonite and if you can, stay on that star for the next week - all 
night time-series as long as you can go.  I'd can help you choose a star 
so that we can get coverage as many as we can for as long as we can.  
All data should be reduced from Dr. Sarty's chart values on his website 
& sent to the AAVSO International dbase.  The list of HMXBs covered this 
run:

I will be doing repeated spectra of these stars over and over as long as 
it is clear.  We are looking to determine orbtial periods, so we need 
lots of data - both nightly time series and over the next nights and 
weeks.  We also need photometric data to correlate to the spectra I am 
taking.  :-)  Can't be snowing everywhere!


Also - if you can, log into the chat group for the next week.  I will be 
posting results and requests throughout the next 7 days.  Please - if 
you are going to help out, post what you are running on either here or 
on the chat group, and I will then be able to assign observers to stars 
which are not being covered.

Thanks to everyone in advance!
