| Proposal | For the completion of an analysis for the variable star NY Vir two follow-up observations of 40 minutes each are requested. This eclipsing binary star has a period of about 0.10106 days and varies in brightness between 13.3 and 14.22 mag V. It is required to have exposure times of maximum 30 seconds, ideally 10 seconds, for each frame. Any primary (pri) transit as listed here https://www.as.up.krakow.pl/minicalc/VIRNY.HTM is fine for observation. Total time of observation is 40 minutes, so an observation should start 20 minutes before and end 20 minutes after the given mid-occultation time. Best regards, |

We will consider this proposal, but it is incumbent on you to provide the times of observation for a given AAVSOnet telescope when it comes time to schedule the observations.

Hi, thanks a lot for considering the proposal. Yes, on request I will then provide the observation times. I was not sure how long the waiting time will be and with an orbital period of 0.1 days, I hoped that this could be sorted out in case of allocation when it comes to it. Thanks again!

The project has been approved. Ken will work with you on the timing of the observations. It shouldn't be too difficult with that short of a period.

Marvin; IF the full period is truly only 2.4 hours, rather than wrestle with exact mid-eclipse timing, we should just run a 3 hour time series for 2 days. It will easily catch the entire eclipse. To use a 10 sec exposure at the desired magnitude, it should just be run on a larger scope (FSM) such as mpo61. Make sense?

Hello Kenneth,
yes this sounds reasonable, if that is within the possibilities regarding available time slots. Thanks a lot!
