Cool. This will be an interesting one for me to work on. It 
transits about 10pm, so we don't have a lot of time before it 
starts to descend into the muck. Again, I'd like to encourage 
y'all to grab some data. I was thinking maybe I'd switch to Rc 
since I can get better S/N. Perhaps someone could help us fill 
in V and Ic?

Thanks!
