Proposal

TARGET:
NT Cam is a DSCT with minimal time series observations in the AAVSO observation database. The star appears to exhibit bimodal behavior with magnitude varying between 12.675 and 13.175V and a period of 0.082417d (118.680 min). Supplemented time series observations will allow for a worthwhile analysis of this star’s apparent behavior.

MOTIVATION:
- Gain experience with AVSONet and the JAAVSO publishing process
- Take full advantage of unused AAVSNet resources
- Gerry Samolyk has expressed a willingness to provide mentorship for this project

OBSERVATION REQUIREMENTS:
- 6 to 8 time series observations over the next 5 months
- Each time series should cover a minimum of 7 hours to ensure 3 complete cycles (Four complete cycles per run would be more desirable) - consecutive cycles will increase the value of each run and reduce the possibility of false frequency detection
- It would be highly desirable to use multiple telescopes at different longitudes on a given night. This would increase our ability to detect multiple frequency behaviors. The more consecutive cycles the better.
- Any given run could be separated by as much as two weeks. This is a soft requirement, greater or lesser separation times are acceptable to accommodate telescope demands.
- Initially, I am assuming, based on the telescope capabilities, that images will require 3 to 4 minute exposures. In recognition of the demand placed on the assigned telescope(s) for a given time series run, each image in the time series could be paused for 1 to 2 minutes, thus allowing other short period exposures from other users.

Some concerns that exposure times would be too long on the BSM systems but Arne will do some preliminary observing to see how well it works.

Super, Thanks for the feedback

I have not received feedback on the status of this proposal. Has there been a determination?

Thanks
