Submission Guidance & Helpful Links
Planning for Hinode operations is performed on a three month cycle that is updated monthly. At the end of every month a monthly meeting is held to confirm the observations for the coming month and to lay out the broad objectives for the second and third months.

The cut-off for consideration is the 14th day of each month. For example, requests for observations received between the 15th of June and the 14th of July will be presented and discussed at the monthly meeting held at the end of July.

It is recommended that proposers make their submissions as early as possible, so that the Science Schedule Coordinators (SSCs) have time to refine the proposals to fit the current Hinode situation.

Late submissions may be considered only exceptionally, if scheduling conflicts can be easily resolved in the operation planning meetings.

For more detailed information, refer to the following:

Title of Proposed Observation *
Your answer
Proposer name[s] *
List primary proposer name first. Provide given name first.
Your answer
Proposer email[s] *
List primary proposer email first. (The email required above is for submission form correspondence.)
Your answer
SSC Points of Contact *
Main Objective *
One line summary summary statement of main objective.
Your answer
Scientific Justification *
Short statement describing the observation and scientific justification. This should be as short and concise as possible, but it should still contain all the key details. This statement is important because Hinode's limited data volume situation may make it necessary to modify some planned observations on some days. The Hinode team will refer to this statement when setting priorities for which observations to perform.
Your answer
Hinode Calendar
Please see for important planning information (e.g., Hinode & IRIS eclipse season, Focused Mode period, etc.)
Dates *
Enter "ToO" if not specific. 1. Provide the start and end dates with reason. 2. Provide the minimum number of observation days during the period. 3. Provide desires and requirements for continuity of observations, for example: "three consecutive days are desired, but not required," "three consecutive days are required," or "it is not necessary for observations to be on consecutive days."
Your answer
Time window
Time window in day, if required. 1. Provide the "minimum" duration with the start and end times in UT, if it is a coordinated observation with ground-based or space-based observatories. 2. Specify whether any short interruptions (e.g., for ten-minute synoptics) are allowed over the observing periods.
Your answer
Target(s) of interest *
1. Clearly specify the target of interest. [Active region, quiet Sun, on-disk, near limb, limb, polar region, etc.; More specific description of the target, if required.] 2. Indicate whether it is a target of opportunity (TOO). If so, suitably describe the target. 3. If a suitable target does not exist during the specified period, we may not perform the proposed observation during that period.
Your answer
Required Hinode instruments and priority of observables.

* The Hinode team will take into account the stated priorities if it is necessary to make adjustments to the proposed observations to fit in the day's available telemetry, etc.

* Specify which Hinode instruments are really required for the observation.

* Specify required observables (cadence, FOV vs pixel summation, wavelengths etc), with priorities, for the primary required Hinode instrument(s).
- Provide rough estimate of the total data volume to be collected, if possible. See section 3 for estimating the total data collected.

* If support from non-primary Hinode instrument(s) is also desired, give a rough idea regarding preferable observables (cadence, FOV vs pixel summation, wavelengths etc).

* For IHOPs (IRIS/Hinode Operations Plans), specify the requirements for the IRIS observations, ideally with:
- an IRIS OBS-ID (for details see
- alternatively, requirements for IRIS FOV, raster mode, raster cadence/exposure time, summing, slit-jaw choices

SOT requests *
Enter "None" if no SOT observations needed. Note: SOT/FG is no longer available. (
Your answer
EIS requests *
Enter "None" if no EIS observations needed.
Your answer
XRT requests *
Enter "None" if no XRT observations needed. Note: The Ti-poly and C-poly filters are no longer in use due to the visible light leak. (
Your answer
IRIS requests
Indicate if proposal has been submitted to and selected by the IRIS team (IRIS POC Bart De Pontieu -- bdp (at) lmsal dot com).
Your answer
Additional instrument coordination
(ex. BBSO/NST)
Your answer
Previous HOPs *
List of past HOPs in which the present proposer was the PI, and the publications/outputs from those HOPs. Indicate if no prior HOP submissions.
