Goal: obtaining spectra of the relatively faint comet 88P/Howell. There are 7 identical OBs of 1h each (exp.time), that can be executed only at the very end of the night, one per night (because of airmass constraint). Requirements (cf README for more details): 1. all OBs should be executed between April 5 and 30!! 2. target is visible only at the end of the night. Because of airmass constraint, only 1 OB per night can be executed (please note that exposure can be extended for 10-15min into twilight). 3. you will need to edit the OBs and enter the following information (from the 073.C-0525A.001.eph file): precise coordinates, additional tracking velocities (given in "/sec) and Position Angle (PsAng). 4. acquisition should be done on the center of light (nucleus) of the comet.
