[vsnet-alert 13778] Re: Last minute request for observations!

[Tom Krajci]

Astrokolkhoz covered this target last night with telescope K35 (C14, V 
and I filters).

A quick examination of uncalibrated images shows the object to be near 
magnitude 17.

We will continue to cover this target nightly, weather permitting, until 
25 Oct.
