Visuals?

What about visual observations, say fainter than the outburst magnitudes?

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

Fits=images right?

Elizabeth

The alert notice does not specify the required IMAGE format.. Do they need jpg, tiff, gif, or fits?

Best!

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!

Thank you, Mike! Very useful

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,

V416 Dra and V1239 Her

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

AAVSO Alert Notice 586 fits

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!
