[vsnet-alert 13139] Re: DR UMa : irregular variations?

[Tom Krajci]

Initial images from Astrokolkhoz show DR UMa near mag 18 at JD 
2455663.6.  This is too faint for me to cover with my telescope.  I will 
stop covering this target unless someone notifies me that it has 
brightened to mag 17 or brighter.
