| Proposal | Alert Notice 377 requests observations of High Mass X-Ray Binaries (HMXBs) in support of radial velocity observations. HMXB V1008 Cep does not appear to have any observations in VSX. Therefore, I would like to obtain images in Johnson-Cousins VBRI photometry. Specifically: V band: 60 and 120 seconds Please schedule 2-3 times a week starting as soon as possible and ending June 1.2023. Thank you. |

Note that VSX shows 75K+ observations but the LCG doesn't show any. Arne will find out why.

Dave:
Why did you select the two exposures? The target exhibits a relatively small rnag range. Easy to get reasonable/adequate SNR with one exposure. We define the exposure for proposers on the basis of the mag range and the scope aperture, unless there is a specific need for something unusual. What is the color of the target?
BTW, there are observations in the LCG. They are just prior to 2020. Take a look.

BTW, Alert 377 was from 2020. Looks like no further work is being conducted. What will you do with this data? The PI will do nothing.
The RA of 22 hours transits at 1100 AM local. Will be low in north at night. Tough to see in most AAVSOnet scopes.

Ken,
Thanks for your feedback. I'm aware of the issues you bring up. I'm trying to learn how to use AAVSOnet, so this is all more or less experimental to gain experience. Thanks for all your help with this.
Dave
