Phase I Proposal
The normal Observing periods are:
The HET Board of Directors have announced that for Science Operations
the LRS2, VIRUS and HPF instruments. Dark time will be dominated by HETDEX observations as the highest priority.
- YYYY-1 (Dec-Mar of year YYYY)
- YYYY-2 (Apr--July of year YYYY)
- YYYY-3 (Aug-Nov of year YYYY)
Please contact your local HET or TAC representative to find out how your institution is going to run Phase I proposals and TAC allocations. For any other questions please contact the HET resident astronomers at astronomer(at)het.as.utexas.edu.
To address the needs of programs that can require Priority 0 time for rare high-scientific-priority
events (e.g., gravitational wave events) that are expected to occur at a rate of less than one per
trimester, the Board is creating a new category of project that is evaluated by a Board-appointed
committee and assigned outside of the current institutional process. (If the proposers wish to
pursue individual institutional time, they could certainly do so.) This process is intended to
minimize the impact on any given institution’s high priority time when no events are triggered.
To apply for consideration, a PI would assemble a team and present a proposal to the HET
Board Chair. In addition to the science justification and responsibilities of the team members,
the proposal should explicitly detail the process for event triggering. It is strongly encouraged
that such a proposal be circulated to scientists at all institutions prior to submission to create a
broadly-based team. The HET Board would decide on an allocation for the Priority 0 time; this
allocation would not be removed from the amount of time assigned to the institutional allocation
committees. If time was approved, the PI (and her/his designated representatives) would be
authorized to activate the observations if the event occurred. If an event is triggered time will be
charged to participating HET partners proportional to partner shares. In any trimester that such
a program was activated the TAC programs of the institutions in this proposal will be affected,
as the used time would be immediately applied to those partner shares.
If the project is not activated, then all partners’ observations and charged time would proceed as
if the project did not exist.
Phase I involves the interaction between your TAC and you the Principal
Investigator. First you should read what each TAC requires. Then
you should become familiar with the observing procedures and capabilities
of the HET.

You can get information about the telescope, instruments and calibrations
in various locations in this web site. It is important to plan for extra time
for overhead or special calibrations. Below we list some of the more
important links you may need.
