Abstract I propose to observe the newly discovered gamma ray Nova (GRO J1650-40) with the Planetary Camera and Halpha and R broadband filters. This is to search for optical counterparts of the high velocity gas seen by the VLA to be ejected in the last few days by the nova. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

GENERAL FORM Proposal 5761 PI: Michael M Shara Proposal Title: Narrowband Imagery of a gamma ray Nova ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Michael M Shara 3470 USA ------------------------------------------------------------------------------------ 3. Description of proposed observations. Two orbits of DD time are to be spent imaging the nova and its ejecta. 4-6 images in Halpha, and four in R are requested. The Halpha and R images can be taken in any order so as to maximize time on target with the shutter open. The Halpha images should be of 900-1200 seconds duration, and need not be of exactly equal exposure time. (Neither should Halpha exposures shorter than 600 seconds be taken). The R exposures should be of 45-90 seconds duration. Again, strict equality is unnecessary. All exposures should be taken consecutively (i.e. no gap between the orbits). ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. This project demands high angular resolution to study ejecta expected to be 1 arcsecond in scale. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Due to the nature of these observations, we request to complete the observations as soon as possible before the target enters the solar exclusion zone in later October, 94. ------------------------------------------------------------------------------------ 9. Description of previous HST work. P2472 Shara, P.I. and Paresce Co-I Interacting Binary Stars in the Cores of Globular Clusters Six hours of HST/FOC time to search for large-amplitude variables (>0.3 mag) in the globular NGC 6752. Data successfully taken, analyzed, and in press. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). STScI will supply full salary of Shara. Support will be requested for an SDA's time and page charges. ------------------------------------------------------------------------------------ 11.
