Observe the following 3 targets. Make sure they are well-exposed, but not saturated. If necessary because any part of the spectrum is saturated, adjust exposure time accordingly and take another 3 spectra.

EGB 5, NGC 6026, LSIV-12.111, and NGC 6891 have highest priority (but airmass may be too high).

Make sure that there are no saturated emission lines in any of the spectra (take another 3 shorter exposures if so).

General Notes: Pri: Target priority. 1 = observe object if possible 2 = extra targets; observe only if no Priority 1 target is available 3 = backup targets; low priority RA & Dec: all coordinates are accurate to 1"; charts can be generated by operator as necessary using LEDAS or DSS. Charts for many objects were prepared at telescope in February and should be available. Cmp: 1 means take comparison spectrum only before target exposures; 2 means before and after ..............................................................................
