I would like to cover the forthcoming eclipse of the Symbiotic star V1413 Aql whose mid time is due in February 2015. The field is too difficult to get from home, even though the altitude is not bad during the early morning hours here in Birmingham, England (I have very poor horizons).

I require telescope time to cover the period from now (January 9th 2015 or as near as possible) to the end of March 2015.

I would only need V filter, and I would expect the eclipse to be around 2 mags deep to around mag 15 (assuming the out of eclipse magnitude is 12.5 as my last data point suggests). I have revised the ephemeris slightly from past visual observations (paper published in BAAJ), and I am keen to see when mid-eclipse actually occurs. I would not need to target the object after the end of March 2015.

Target RA (H.HH) Dec (D.DD) Magnitude Telescope Observation Frequency Expiration Date Proprietary Term
V1413 Aql 19.063014 16.43808 16.0–12.0 No

The TAC suggests adding B and Ic observations to increase the scientific return.

Thank you for your comment. Taking your advice, please add B and Ic to the proposal.
