GENERAL FORM Proposal 5152 PI: Dr. Peter Jakobsen Proposal Title: SHAPE AND EXPANSION OF SN1987A EJECTA ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Dr. Peter Jakobsen ESA, ESTEC NETHERLANDS X Dr. Ferdinando Machetto STSCI USA X ------------------------------------------------------------------------------------ 3. Description of proposed observations. Direct images of SN1987A will be taken in the F275W and F501N filters. Neither the precise duration (to within, say, 20%) nor the sequencing of the individual exposures is critical. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. This proposal is a direct continuation of the FOC/GTO 1259 and 3874 proposals. Aside from COSTAR, the proposal utilizes an identical instrumental configuration and exposure sequence. ------------------------------------------------------------------------------------ 9. Description of previous HST work. Miscellaneous FOC/GTO observations. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). Access to several of workstations running IRAF/STSDAS. ------------------------------------------------------------------------------------ 11.
