Section II - Time Request

A time request is required for this semester. If you also require (and justify in the proposal) time for next semester, please enter it in the second box below. Please address any questions to Robert Minchin

Total hours requested for this semester:
Hours for next semester, if relevant:

How many hours have already been used for this project?

If this project continues beyond one year, please estimate total additional hours to complete it (not including this request):

Search the past schedules for time allocated by project number: Schedule search

To compute the LST rise and set times for your source(s) at Arecibo you can use: Rise and Set Times

Time Distribution:

Use more than one line only if necessary. If this format does not suit your needs, please describe time requirements in the area below.

Specify Time system: LST Local Sidereal Time AST (Atlantic Std.=UT-4) UT

Times requested in first semester (hours, or hh:mm if appropriate)
Interval Start Interval Stop Days Needed at this time interval
Begin End Number of Days
Begin End Number of Days
Begin End Number of Days
Begin End Number of Days

Describe constraints on the days requested. For example: range of calendar dates preferred, or 2 runs of 3 days, spaced 5 days apart, etc. If your observations are triggered by special circumstances or require certain conditions, describe them here. Scientific reasons for the time distribution should also be described and justified in your proposal.

Please enter the minimum usable block of time in a single session for help in scheduling. In case a time slot becomes available, let us know how short a time would be usable for you in your LST range. Remember that the telescope can take up to 15 min to slew to your target, depending on where the previous observer has left it.

Minimum Useful Single Session Time

If you are also requesting time in the following semester:
Interval Start Interval Stop Days Needed at this time interval
Begin End Number of Days
Begin End Number of Days
Begin End Number of Days
Begin End Number of Days

Describe constraints on the days requested, as above.

Data Requirements

Please estimate the amount of data you expect to collect each day, or observing session. This will ensure that we have enough storage to meet everyone's needs. If you need more than 1 TB please discuss your storage requirements well in advance of your observing time with your support astronomer.

less than 100 GB
100 GB - 1 TB
more than 1 TB

Section III - Instrument(s) Required:

Click here for available receivers.

For Radar observations, check transmitters below. To use only the receiver, click appropriate box under receivers.
Gregorian receivers Carriage House receivers Transmitters (Radar Instruments)
327 (0.31-0.34 GHz) 47 (44-50 MHz) 47 MHz Carriage House
430 (422-442 MHz) 430 CH (425-435 MHz) 430 MHz Gregorian
705-825 MHz S-Band radar 2380 MHz
L-wide (1.15-1.73 GHz) Ionospheric Heater 5-8 MHz
ALFA 7-beam (1225 - 1525 MHz)
S-low (1.8-3.1 GHz)
S-radar (2.33-2.43 GHz)
S-high (3.0-4.0 GHz)
C (4.0-6.0 GHz)
C-high (6.0-8.0 GHz)
X-High (8.0-10.0 GHz)

For 430 MHz Radar Observations, is Dual Beam configuration required?



Is night-time required for your observations?

Yes, night-time is required

Night-time is preferred

No, daytime is acceptable

Check that your LST is in night-time during the requested semester: Nighttime

Atmospheric Optical Observation Instruments
Check technical data for Arecibo optical instrumentation for details on using these.
Tilting-Filter Photometer
Fabry-Perot Interferometer

I plan to use my own instrument (specify below).

If you are requesting several instruments, please describe briefly if all are needed each run, if one is primary and other(s) are backup, etc. Refer to proposal if description is extensive. Also if applicable, give a description of any special equipment needs, hardware, software or recording media.

Section IV - Special RFI Considerations

For general information about the RFI situation at Arecibo Observatory, click here. You MUST request RFI protection now if you think you will need it, since arrangements must be made far in advance of the observations.

Enter the frequency ranges to be used (in MHz):

Example: 1220 - 1250

(please separate each range with a carriage return)

You MUST check either yes or no for each item below:

Yes, I need protection from IRIDIUM at 1610.6 - 1613.8 MHz (Observations must be scheduled between 10pm and 6am EST or 11pm and 7am AST.)

More Information

No, I do not need protection from IRIDIUM.

Yes, I need coordination with Punta Salinas radar for my observation within the band 1222-1381 MHz. More Information

No, I do not need coordination with Punta Salinas radar.

Yes, I need coordination with GPS L3 at 1381 MHz. More Information

No, I do not need coordination with GPS L3 at 1381 MHz.

Section V - List of Targets

List your targets (leave blank if this does not apply, i.e. for atmospheric observations).

NOTE: If your list is more than 30 lines include the list as part of your proposal.
If appropriate, give LST visibility for your targets.

To compute the LST rise and set times for your source(s) at Arecibo you can use: Rise and Set Times

Example: Object RA Dec LST rise-set, or Object type, or criteria for searches, etc.

Policy on Acknowledgements and Press Releases

We remind all users that a proper acknowledgement of the Arecibo Observatory should be included in all publications and press releases resulting from data obtained at the Arecibo Observatory. This is in line with the NSF's request for recognition of its facilities.

If a press release is produced from data obtained at the Arecibo Observatory, we ask that you please coordinate with our press officer, Ruth Torres.

PLANETARY RADAR USERS: The Arecibo Observatory planetary radar system is funded by a PI grant through NASA's Near Earth Object Observation (NEOO) program (grant # NNX12AF24G). All press releases and manuscripts produced with this system should include proper acknowledgement to the Arecibo Observatory and NASA's NEOO program. If an object is of interest to NASA, users acknowledge that upon request they will provide press-worthy data to be released to NASA.

End of the Cover Sheet portion of your Observing Proposal.

Press Preview to be sure that your cover sheet is correct and complete. You may return to the form to make changes if needed. You can save your PDF coversheet at this time if desired.

If you have any problems with the form contact Robert Minchin for assistance.

To complete your observing proposal, you must also send either a postscript file or PDF file as an attachment with your scientific justification, no more than 4 pages (7 for large), to See Proposal Policies for more details.

If your file is large (bigger than 50 MB) contact Robert Minchin for submission instructions.

After successful submission of the cover sheet, a temporary ID (PI last name plus a 12 digit number) will appear on the screen. This may take several minutes - please be patient. Please enter ONLY this temporary ID - with no additional words - into the Subject field when you email your scientific justification, for ease of processing. If for some reason you do not have this ID, enter your last name.
