Major Instrument Modes: Dic1_390+564

RA Range: MOV target

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance):
2.0, CLR, 2.5, 1.0, 60


Pre-imaging run? No! Chilean run? No! Special calibrations? No!
Time critical? Yes! ToO? No! Carry-over run? No!


Special Remarks:
*very* time critical: MOV target (comet Howell) programme that must be executed between April 5 and April 30.


 

 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.
