Abstract

Hubble had already seen a full cycle of operation with the newly installed and repaired instruments calibrated and characterized. The Advanced Camera for Surveys (ACS), Cosmic Origins Spectrograph (COS), Fine Guidance Sensor (FGS), Space Telescope Imaging Spectrograph (STIS), and Wide Field Camera 3 (WFC3) were all close to nominal operation and were available for Hubble observing proposals in Cycle 19. The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) was available for proposers as well. However, when the Call for Proposals was issued, the decision on when the NICMOS cooling system would be restarted had not yet been made, and the instrument was inactive. Nevertheless, the proposers were advised to assume NICMOS would be available during Cycle 19. The Phase I deadline for Cycle 19 was February 25, 2011. As usual, although some proposals were submitted weeks before the deadline, the majority arrived on the last day, with a rapid rise in submission rate as the deadline, 8 p.m. Eastern time, approached. Due to power issues in Baltimore, Maryland, the deadline was extended incrementally: from 8 p.m. to 10 p.m. on 2/25; then from 10 p.m. on 2/25 to 3 p.m. on 2/26; and then from 3 p.m. to 6 p.m. on Saturday 2/26 (the final deadline). We received a total of 1,007 proposals, after accounting for duplications and withdrawals. Review process Members of the international astronomical community review Hubble proposals
