CLIMB Observing Run 2011Apr

Observing Strategy:
We would like to observe some of our primary YSO targets with CLIMB on the telescope configuration S1-E1-W1 (first priority) and S2-E2-W2 (second priority). If telescope S1 is not available, please replace with telescope S2 (and vice versa). For the POP setup, I propose S1(POP5)-S2(POP4)-E1(POP1)-E2(POP1)-W1(POP1)-W2(POP5).

First night: I suggest starting on S1-E1-W1 (POPs: 5-1-1) and to observe HD142666 (LT 23.9-1.8), HD144432 (LT 0.7-1.5), AS205A (LT 0.1-2.3, only with excellent seeing conditions), HD150193 (LT 0.9-2.4), HD163296 (LT 1.9-3.8), MWC297 (LT 2.7-5.0, only with excellent seeing conditions), HD179218 (LT 4.6-5.5).

Second night: If the first night was relatively successful, I suggest switching to S2-E2-W2 (POPs: 4-1-5) and to observe HD142666 (LT 23.9-5.1), AS205A (LT 24.0-5.4, only with excellent seeing conditions), HD144432 (LT 0.7-3.4), HD150193 (LT 0.9-5.8), MWC297 (LT 2.7-5.8, only with excellent seeing conditions), HD179218 (LT 5.2-5.8).

Notes: (1) The targets AS205A and MWC297 are very promising, but are likely difficult due to the low V-band magnitude. Please try only under exceptional atmospheric conditions. (2) Complements with our VLTI MR/HR-data

For the first half nights, we would like to observe Regulus and some its calibrators with PAVO 2T. The best configurations are (S1, S2, E2) - W2, pops: 1 - 5.
