Proposal

We would like to take follow-up images of the star V1128 TAU which is a contact binary star (EW) and has a period of 7.328921 h.

This fall, on two occasions, we observed it and found that its minimum (and maximum) were shifted compared to the ephemerides and we would like to know more. We therefore need series in B and V filters of several hours (3h. minimum) in order to find them and validate its period as well. Retakes would probably be necessary if the first observations are not complete.

Thanks in advance!
