Frequently Asked Questions
Access to Palomar telescopes is based on your standing with a Palomar project or partner constituency. For example, partners in the Hale/P200 telescope are Caltech, JPL, NAOC, and Yale. Each of these partners manage their P200 time allocation independently and differently, so we’ll have to direct you to each of the partner time allocation process as appropriate for your situation.
If you are affiliated directly with Caltech, you can start by consulting our COO telescope time solicitation page.
Palomar telescopes are typically scheduled by observing semester; the A semester is February – July inclusive, and the B semester is August – January inclusive. Proposal solicitations typically are issued approximately five months before the start of the observing semester (so early March for B and early September for A semester), and allocation decisions/time assignments are typically announced two months before the start of the observing semester (so early June for B and early December for A semester).
If you are affiliated directly with Caltech, the COO telescope time solicitation page will provide information on solicitation, proposal format, submission deadlines, and notifications specific to the Caltech constituency.
The semester observing schedules are developed based on proposal inputs for designated programs from each of our constituencies. In particular the program cover sheets (that capture program scheduling preferences and constraints, and instrument configurations) are the key drivers in the scheduling process. We do our best to integrate all the program objectives, preferences, and constraints into a balanced, efficient, and cohesive telescope schedule. An important efficiency consideration is the degree to which we can “block schedule” programs with similar instrumentation needs together; minimizing instrument changes reduces wear and tear on the instrumentation and summit team.
Draft schedules are reviewed with the key observatory stakeholders (allocation contacts for each of our constituencies, and observatory personnel who must implement the schedule) before the schedule is finalized and posted on our reservation system web tool.
We get this a lot…
Inevitably individual program observers request changes to the schedule once it is posted. The Observatory looks to the change advocate to propose an alternative schedule variant and coordinate that proposal with all impacted programs in advance.
Email requesting a proposed telescope schedule change (copying the administrative PIs of all programs impacted by the proposed change) is sent to (COO Deputy Director) Andy Boden (bode [at] astro.caltech.edu), who will coordinate with Observatory personnel to assess the operations impact of the proposed schedule change. If the assessed impact is acceptable, the schedule change proposal will be accepted and implemented, and the impacted program contacts will be notified of the change.
Observatory judgement in telescope schedule change requests is final.
If you really cannot make your assigned telescope time then you should advise (COO Deputy Director) Andy Boden (bode [at] astro.caltech.edu) that you are returning the telescope time for reassignment. Please be specific on what dates are being returned, and with as much advance notice as possible so as to maximize the chances the time can be usefully reassigned to another investigation.
Instrument configuration is accomplished through the the online reservation system, and in particular through the Run Detail page/Add Settings link. A valid reservation system login is required.
Only instruments assigned to/approved for your run will be available to you through this process.
To edit the instrument setting for an observing run (possible up until 4 days before the observing run), you select the observing “run” number on the observing schedule.
Clicking on the observing “run” number will bring up the details of the observing run.
Here’s an example of the details for an observing run. You’ll notice that there is not a link allowing you to edit the observing setup for the observing run because the person logged into the reservation system isn’t either the Principal Investigator or the Lead Observer. If you are logged into the system with the account of the Principal Investigator or the Lead Observer then a link appears next to the instrument name allowing you to access the associated “green sheet” where you can specify the required instrument parameters.
By clicking on the “Edit settings” link the “green sheet” for the associated instrument will be displayed (note each “green sheet” is different and customized for the particular instrument).
Sometimes the email address associated with the observing run when it is created does not correspond to the observer’s user name in the reservation system. As a result, the system does not accurately associate the observing run with your account. If this happens then contact the support astronomers in the afternoon (760) 742-2018 and they can edit the observing run to give you access or email jwm[at]astro.caltech.edu concerning the issue. Please let them know your username so they can lookup the correct account.
Instrumentation assignment is defined as a part of the time allocation/telescope scheduling process. Instrumentation changes are controlled because they have the potential to perturb operations.
Nonetheless, situations sometime arise where a change in instrumentation is desirable for your run. This instrument change request process parallels telescope schedule change requests: the run cognizant (either administrative Principal Investigator or Lead Observer—if they are different) submits a request to change, add, or reconfigure an instrument (relative to the baseline schedule), and the observatory will assess accommodating the request based on its operations impact. If the change request is accepted then the observing team will be advised of same, and the instrument configuration will reflect the request.
Users may submit an instrument change request in email to [COO Deputy Director] Andy Boden (bode [at] astro.caltech.edu), (Site Superintendent) Rick Burruss (burrus [at] caltech.edu), or the general P200 support email list (p200Support [at] astro.caltech.edu).
Observatory judgement in instrument configuration/addition change requests is final.
A particular note about secondary instrument addition requests: Observatory policy is to require constituent allocation judgement in the use of secondary instruments (e.g. Caltech requires TAC approval for secondary instrument use). Requests to add a secondary instrument outside the constituent time allocation process will be accommodated solely at the Observatory’s discretion and typically only if there is minimal operations impact.

Through the reservation system. Select your run number on the P200 observing schedule. You will see the primary and secondary instruments listed for your run. Click the “Edit Settings” link for each instrument to enter your desired settings, then press the “SAVE” button at the bottom of the page. Note that your reservation system account must be listed as the Principal Investigator or Lead Observer of the run for you to be able to edit the instrument settings.
You can submit or edit the instrument settings for your run up to four days before your run starts. If you need to change settings after this time period, you must email p200support [at] astro.caltech.edu to request the change.
Observer on-site accommodation are provided at the Palomar “Monastery.” Please see http://www.astro.caltech.edu/palomar/observer/observertravel.html for an overview of observer travel resources, including information about the Monastery.
First login to your account on the reservation system and select the “Monastery” link on the left hand side of the screen. You will be taken to a calendar view similar to the one depicted below.
Note that each day in the calendar has a small “house” like icon below the moon phase image. Click on the “house” icon and a new form will come up that allows you to make a reservation.
Fill in the required items in the form (note the red asterisk denotes a required field) and then hit “SAVE.” Once you have saved the reservation, your name will be displayed on the Monastery calendar under the days you are scheduled to stay at the Monastery.
Please see the observer travel page. In particular please note that there are significant financial “incentives” to book your Monastery reservations well in advance. Palomar is remote, so this advance planning information is important for our Monastery service providers.
Log into the reservation system and click “My Profile” on the left, then click the “Edit My Profile” link at the bottom of the page. There is a field where you can enter any dietary requests you may have. These preferences will be stored for Monastery staff reference for all your subsequent Monastery stays.
Please see the observer travel page.
Please see the observer travel page for an Observatory compound map.
Please see the observer travel page.
When you arrive at the Observatory, first go to the Monastery. There you can sign up for a room and get a key to the dome. From the ground floor of the dome, you can take the elevator to the observing floor (Press “O” in the elevator) to get to the data room.
First-time Palomar visitors should refer to the Observatory compound map in the observer travel page.
Remote observing (RO) at P200 is accomplished by VNC computer and videoconference connections. Please note that not all P200 instruments can support RO (supported instruments are DBSP, TSpec, WIRC, WaSP, LFC, and CHIMERA).
Palomar RO information and Cahill RO reservations are booked through the COO remote observing page.
Please note our Cahill RO policies prioritize Keck RO over Palomar RO (Palomar RO reservations can be “bumped” by a subsequent qualified Keck request.)
You can start calibrations any time after the lights are turned off in the dome. During standard time, the lights are turned off at 3pm PST. During daylight saving time, the lights are turned off at 4pm PDT.
If you would like a tutorial or refresher on how to use the instrument, it is best to come to the dome an hour before you plan on taking calibrations. Otherwise, we recommend arriving when the lights are turned off in the dome so you can take any necessary calibrations.
The P200 observers are in charge of setting dinner time. When you arrive, check the chalk board in the monastery to see what the current dinner time is. If you would like to change it, inform the monastery staff of your preferred dinner time.
The P200 telescope operator can open the dome any time after sunset, given safe weather conditions. When you meet the telescope operator, let him or her know when you’d like to start your observations.
