8552( 3) - 01/05/00 17:51 - [ 1] PROPOSAL FOR HUBBLE SPACE TELESCOPE OBSERVATIONS ST ScI Use Only ID: 8552 Version: 3 Check-in Date: 05-Jan-2000 17:50:19 1.Proposal Title: The Crab Synchrotron Nebula: Short Version ------------------------------------------------------------------------------------ 2. Proposal For 3. Cycle GO/DD 8 ------------------------------------------------------------------------------------ 4. Investigators Contact? PI: Jeff Hester Arizona State University ------------------------------------------------------------------------------------ 5. Abstract Obtain HST observations to accompany Chandra observations of the inner Crab synchrotron nebula. ------------------------------------------------------------------------------------ Observations Description ------------------------ The program is a temporal monitor of the dynamical structure near the center of the Crab Nebula. F547M will be used to image the Crab on each of 5 1-orbit visits, separated by 10 days. These visits will be coordinated with observations obtained with Chandra.
