AAVSO Alert Notice 586 announces an observing campaign 2017 July 9 - 11 on 20 CVs, obtaining images only (no magnitudes). Please see notice for details and observing instructions.
Many thanks, and Good observing,
Elizabeth Waagen, AAVSO HQ
What about visual observations, say fainter than the outburst magnitudes?
Mike
That helps too, especially for the brightest targets! Thanks for your interest in the campaign.
Clear skies, Roque
Hi Mike,
I have asked Roque Ruiz-Carmona, the PI, about visual observations. Either he or I will post here with an answer. Thanks for asking!
Good observing,
Elizabeth
I plan to observe PTFS172bs (SS Cyg), PTFS1719dy (WY Sge) and PTFS1620k ( WZ Sge ) on July 10 weather permitting.
Dear observers,
At the observatory of Roque de los Muchachos in La Palma, the night is good except for the bright full moon. I hope you also enjoy clear skies!
Cheers, Roque
Roque
How can I send you my FITS files from last nights observations?
VAastro
Hi Elizabeth,
How can we submit our FITS files to the 2017 20PTF campaign?
Thanks
VAastro
Hi VAastro,
The PI has requested only images, not FITS files. Please check the Alert Notice for requirements and instructions. Images (maximum size 40M) should be posted on this thread.
Good observing,
Elizabeth
OK, Thanks Elizibeth
Attached are images. They are 15 stacked 120 second exposures. Filter and JD are in the file name.
VAastro
Thanks a lot for your images, VAstro! No outburst yet...
Clear skies, Roque
Elizabeth
The alert notice does not specify the required IMAGE format.. Do they need jpg, tiff, gif, or fits?
Best!
Pablo
Dear Pablo,
Fits files are preferred, but any format will do. Some observers have used links to storage services such as Dropbox if the images are too heavy. The purpose is just to determine whether the systems are in outburst. or not.
Thank you so much for your interest in the campaign and clear skies!
Roque
This one appears not to be in bright outburst as of July 10 09:00 UT (<14.4 vis.) Thanks for the campaign during full moon
Mike
Thank you, Mike! Very useful to know!
Not my personal decision to place the campaign with full moon, I have no power over the schedule at the William Herschel Telescope
Cheers,
Roque
A little better visual observing this evening, I could squeeze in some more faimter obs during the brief window around moonrise. Neither of these stars seems to be in outburst.
V1239 Her <15.2 Jul 11 06:43UT
V416 Dra <14.6 Jul 11 07:37UT
Mike
Excellent, Mike! Thanks a lot!
Roque
These are the ones that I was able to squeeze in. Extreme light pollution from moon and other lights in the area, Celestron C14 Edge HD with SBIG STF8300MM. I tried V and B but since you needed images only I settled for Lum. Fully calibrated, BDF and plate solved. stacked 10x60 seconds each used different stacking process to get the bes snr possible. There were some donuts left on some and some light rays on others. It's 3 AM (almost) and this is the best I could do. Good Luck and keep us posted!
This is the Dropbox link. This site does not seem to like my fits...https://www.dropbox.com/sh/39lx9zsm5or4ag0/AAAc4WYbq4qu8W01BPI14NkRa?dl…
Best!

Thanks a lot, Pablo.
I already downloaded the images in jpg and fit. Thanks for the effort!
Cheers, Roque
