Says Walt Cooney, discoverer of variable stars UCAC4 427-090942 and UCAC4 425-096646:

            Our dark site now has its first two variable star discoveries. I found these in the Scutum Milky Way and imaged them over several nights in July to get a light curve. They are both W UMa eclipsing binaries with periods of about half a day.

Walt discovered these objects in July from his personal observatory at the dark site, Starry Night Observatory, and submitted them to the AAVSO. The AAVSO has become the central repository for variable star discoveries in recent years via the VSX database. More than 330,000 variable stars are currently cataloged. Walt's discoveries have been submitted and accepted to the database. Attached are the phased light curves for each. 

 Congratulations and Clearest Skies, Walt!
