Proposal	Code: BPEC Observation Use: Monitoring for Alert Notice 744 Use of Data: Submit to AAVSO Database after VPhot analysis I request that images be sent to VPhot Target Star: V1117 HER Magnitude Range: 12 - 14 mag Comp Stars: from X26651AU chart – 138, 126, 142 I'll deal with these in VPhot Observation Cadence: 2X per Evening if time is available, 1X otherwise. Perhaps 1X per evening on 2 different systems? Filters Required: B, V, I Number of Exposures per Run: 2X per filter Exposure Times: Site Owner's Best Guess initially, will review following 1st observing run Start Date: ASAP End Date: TBD Target Name Right Ascension Declination Minimum Magnitude Maximum Magnitude Keep Proprietary Proposal V1117 HER 16 39 06.43 +09 47 55.3 14 12

(4726) Kenneth Menzies — June 12, 2021, 11:48 p.m.: Committed to NH and NM
(37929) Peter Bealo — June 14, 2021, 7:22 p.m.: Ken,
New report puts it at visual mag 15.3. Are the exposure times good for that??

(37929) Peter Bealo — Oct. 22, 2021, 2:36 p.m.: 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?
(2108) Arne Henden — Oct. 22, 2021, 2:52 p.m.: 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.
