The following section in blue was written prior to Hinode changing from X-band to S-band telemetry. Therefore, please bear in mind that these studies are unlikely to be able to run at this time.

However, the discussion of the scientific type of observation is still valid, and many new studies have been designed to have a lower volume for the new telemetry situation. For example, PRY_footpoints_v2 has been succeeded by PRY_footpoints_lite. See Study4LowDataVolume for some more examples of lower-volume studies, though.

This is a list of some studies that I've either designed or used that I think are generally useful.


Consists of two rasters, the first being a 40" slot context raster (600"x512" field of view). The narrow slit raster has a moderate cadence (23mins), wide range of emission lines, 100x240 arcsec^2 field of view. Uses 2" slit.


Similar to above, but more focussed on hot plasma, and uses 1" slit. Also has a 40" slot context raster.


This is a large field of view (460"x384"), 1" slit raster suitable for diagnostic and velocity maps of ARs. The duration is 5hr 40mins and so fits in the inter-synoptic slots nicely.


A high cadence (4mins) raster covering 40x120 arcsec2 with many diagnostic lines, and a 10s exposure time. It is a good diagnostic study for studying flaring activity in active regions.

Eclipse season#

During the eclipse season, it is possible to run studies with a higher data rate than normal during the day period, leaving the night periods empty on the timeline. Some studies that are suitable for running in this way are:


Takes full CCD spectra over a 128x128 arcsec^2 area, with 25s exposure times, and 1" slit. Duration: 1 hour. Data rate: 96 kbits/s.


Takes over 60% of the EIS spectral bands (mainly dropping low sensitivity areas), and covers 105x178 arcsec^2 area, with 40s exposures, and 1" slit. Duration: 1hr 22mins. Data rate: 50 kbits/s. Includes a slot context raster.
