	We would like to observe AB Aurigae (V=7.1, H=5.1) using MIRC-6T. The target is very high priority, so we should record data even if we have only some of the baselines or low SNR. Beyond 100m, the fringe contrast will likely be quite low (<0.2, see Tannirkulam et al. 2008). I propose the following setup, which would require POP changes around LST 03:43 and LST 06:39 (times computed with ASPRO2 for 2011/12/02).

			If you find that AB Aur cannot be observed and it is not possible to switch to CLIMB for the backup program during the night, you might observe 17 Lep (which is an interesting interacting binary star), Theta1 Ori C (=Parenago 1891=HD37022), or other stars from other programs with MIRC-6T.
