If we can get the CVZ during 24, 2003 - Dec 3, 2003 great. If not, then we will resubmit with new exposures (not to exceed 3 orbits) and request the observations to take place about Feb.Mar 2004. Cheers, -Pete Challis Essential Observations of SN 1987A We request Director's discretionary time to avoid a gap in understanding the dev elopment of SN 1987A just at the time when it is changing most rapidly from a su pernova into a supernova remnant. There will be no way to go back in time if we fail to do this now. We would like 3 orbits to image SN 1987A in Cycle 12.
We propose to continue our imaging through the same set of filters used in Cycle 11: in 3 CVZ orbits, we were able to construct fully-drizzled ACS/HRC images in F555W, F625W, F814W, F658N, F502N, F330W and F435W. 0 false false false false SUPPORTED EXT-STAR J2000 00 00 0.00 +00 00 0.00 J2000 No false false ACS-HRC-DITHER-BOX false 19.89 1 0.15 DITHER 4 LINE POS-TARG /var/tmp/OPVisit18931.xml (Tic-Visit :proposal-id 9992 :visit-id "01" :proposal-version -1 :trans-version "20030713" :date "29-Sep-2003 15:57:38.0" :trans-errors '(:WARNINGS 1 :ERRORS 0 :HEALTH-AND-SAFETY 0 :FATAL-ERRORS 0 :CONTINUABLE-FATALS 0) :number-of-orbits 3 :saa-model "27" :si-bright-earth-limb-angle 20.0 :data-volume 1557568 :tdrss-contact-duration 0 ) (Tic-Obset :proposal-id 9992 :visit-id "01" :obset-id "01" :pcs-mode "FGS" ) (Tic-Orbit :cvz T :proposal-id 9992 :visit-id "01" :orbit-number 1 :pcs-time 365 :si-vis-utilization 16371 :dark-offset NIL :dark-utilization 0 :max-dark-utilization 0 :low-sky "N" :pcs-visibility 0 :pcs-gap 0 ) true /var/tmp/OPVisit58965.xml
