CADENCE                       1 spectrum/night for the period 15 December - 31 January
                              
PREFERRED SETUP               echelle, no iodine cell, set to handle Halpha

EXPOSURE TIMES                We wish to probe eta Car nightly during the period of 15 December 
                              through the end of this semester, with 10 minutes (including 
                              overhead) per exposure (5 min to acquire, 1 min comp, 4 min 
                              exposure)

SCIENTIFIC DESCRIPTION        We believe that the new echelle spectrograph on the 1.5 meter 
                              telescope may yield the resolution to thoroughly probe the 
                              optical variability of this "protypical" LBV and resolve some 
                              unanswered questions including, but not limited to:
                              are any of the secondary star's spectral features visible?
                              what is the variability of the unidentified emission feature 
                              at 6307A at periastron? (currently only probed at apastron)

                              Target list:

                              Star                     V   Type     RA(2000.0) Dec(2000.0)

SCIENTIFIC DESCRIPTION        Second semester of 3-year project to monitor LBVs to
                              search for evidence of spectroscopic variations caused
                              by multiplicity. (HD 5980 and HD 269128 are eclipsing binaries).
                              eta Car will be going through its periastron passage and we
                              wish to increase cadence when the star becomes visible again, 
                              making this the only target on our list after December 15.
