New report puts it at visual mag 15.3. Are the exposure times good for that??

I haven't seen any data on V1117 HER in a while. Are we out of season or is it possible to have other AAVSONet assets image it?

Hi Peter,
V1117 Her is at airmass 2 at the start of the night, and that is the current limit. Since it is now in a deep fade, we will loosen the constraints and enable observations to X=2.5 or so, so that you can get a last estimate or two.
