|Proposal Deadline||Estimated Earliest Possible Execution Date|
February 8, 2019 - noon PST mid-April 2019
May 3, 2019 - noon PDT mid-July 2019
|Any DDT proposal submitted after May 3, 2019 must include a brief description of why it was not possible to submit the proposal by the deadline. This text should be included in the "Other Comments" box on the proposal submission webform. The review of time-critical proposals will be done as rapidly as resources allow.|
Please note that the final date for executing Spitzer observations will be January 29, 2020.
To submit a Spitzer DDT proposal fill out this online submission form, which includes:
- Standard coversheet information (PI and Co-I contact information, proposal title, etc, as for a regular General Observer submission).
- Complete Astronomical Observation Requests (AORs).
- A strong scientific justification (must be in PDF format), specifying why the request was not submitted during the normal Call for Proposals and the long-term legacy value of the observation. Please use the templates:
Please upload both the science justification and the AORs via the online form.
Note that requests for DDT cannot be used to resubmit all or part of a proposal that was rejected by the normal peer review process.
