| Proposal | BVRI monitoring of HD 5501 The spectroscopy discussion group is participating in a campaign for Richard Gray on the eclipsing binary HD 5501. It has some very peculiar spectroscopic attributes, and to flux-calibrate the spectra, as well as correlating broad-band changes with spectral line changes, BVRI monitoring is being done by a subset of the group. There is some discussion as to which comparison star(s) are appropriate for this blue target, and so I'm in the process of monitoring a half-dozen of the available comp stars to look for small variability. I started this project as a background target on BSM_NH2, but I'd like to formalize the project. Send images to VPHOT. |

airmass limit of 1.8Let me know when you've created the plan, and I'll disable the one currently running.
Thanks, Ken!- (2108) Arne Henden — Oct. 28, 2023, 11:33 a.m.
