Special Remarks:
The run B of programme 281.C-5004 should be executed sometime between June 20th and July 10th.
Abstract for MTS:
FORS1 long slit spectroscopy and broad band B, V, R & I imaging of Comet 67P/Churyumov-Gerasimenko.
As this is a moving target the actual position, differential tracking rates and slit orientations must be obtained from the attached ephemeris files for the exact time of observation. The accuracy of the given ephemeris is sufficient to allow fast acquistion in all OBs.
As we need spectra of a solar analogue star (taken with the same instrumental setup as the comet) in addition to ESO's standard calibration plan, we included an appropriate observing block named: SolAna_cg67p_lss.
Special Execution Requirements
==============================
As all OBs refer to the same target they could in principle be executed consecutively according to the given priority. However, due to the viewing geometry the target is visible only during the second half of the night in end of June, so that the OBs need to be spread over several (if possible) consecutive nights.
No finding charts attached.
