Special Call for Proposals to Observe Comet Tempel 1 Deep Impact Event
March 18, 2005
Keck Observatory, Gemini Observatory & Subaru Telescope
This is an open call to the world astronomical communities to observe the Deep Impact event on Comet Tempel 1 in July 2005, using the most powerful telescopes and instruments currently available.
In support of the Deep Impact mission to intercept Comet Tempel 1, windows of Director’s Discretionary time have been reserved on the Keck I & II, the Gemini North & South and the Subaru Telescopes. These windows (corresponding to times before, during and after the impact) are:
For Keck, I & II, the
night of July 3rd;
For Subaru, the night of July 3rd;
For Gemini North, the nights of July 2nd, 3rd, and 4th
For Gemini South, the nights of July 3rd, 4th and 5th
[The encounter time is currently scheduled for 06:10 4 July 2005 UT, which is 20:10 July 3rd in Hawaii. These times could move slightly later. This timing means that the comet will have set as seen from Chile, and the impact itself will not be observable there.]
Keck has reserved only the night of impact itself for the high resolution spectrograph, HIRES on Keck I, and the near infra-red spectrograph, NIRSPEC on Keck II. All capabilities currently available on Gemini (except GNIRS and GMOS-South) and Subaru are offered. Selection of the instruments will be based on the proposal’s scientific merit and coordination between the observatories.
The three observatories are inviting joint or individual proposals to all three facilities. Proposers should be aware that the observatory Directors will coordinate the efforts to provide the most complete coverage of the event and to exploit their respective observational strengths. Data from all observatories will be made public immediately after completion of quality assessment.
All proposals can be submitted directly to all (but at least one) of the observatory sites:
For the Keck programs, send your proposal(s) to Randy Campbell at firstname.lastname@example.org
For Subaru programs, send your proposal(s) to Masa Hayashi at email@example.com
Deadlines for proposals are April 30th, 2005. The observatory directors will then meet to choose the programs. Selected PIs will then be contacted to prepare the appropriate phase II material.
