HOP 58 - Active Region Outflows
Hinode Observing Program (HOP)
58 was created to track the footpoint
regions of coronal loops at the edge of an active region continuously
for 6 days as the region rotated from the meridian to the west limb.

format) to find out more details about the science goals and
observations required from each of the three instruments. Some key
- During the 6 days the number
of XRT synoptics is reduced to two
- The EIS data recorder
allocation is increased to 32% (from 15%)
and the SOT allocation is reduced to 53% (from 70%). The XRT allocation
remains the same (15%).
- The approximate cadence of
the EIS observations is 45 minutes.
- The EIS observation is
intended for tracking longer timescale
variations over a large spatial area.
- A single EIS raster is to be
used for the entire campaign,
PRY_footpoints_HI, with PRY_slot_context used occasionally for context
The sections below describe
runs of the HOP.
Run 1: 2008 January 10-15
This run was badly affected by
the reduced Hinode telemetry which
was approximately half the usual rate. The target was a weak active
region which was close to an equatorial coronal hole.
of the EIS studies run for the HOP are available. PRY_footpoints_HI
could only be run sporadically during the 6 days, and the COs scheduled
other low data rate studies to fill in parts of the timeline (mainly
JTM002). A large fraction of
the PRY_footpoints_HI data are not
presently in the Hinode archive (indicated as 'missing' in the list)
some of these are probably permanently lost.
Fe XII 195 images
from each of the runs of PRY_footpoints_HI are available.
SOHO/CDS supported HOP 58 for
parts of the 6 day period. The study
run was FOOTPT which covered an area of 180"x180" with a 45 min
cadence. A list
of the CDS studies is available.
