Following the discovery of the "dark jets" from the HOP 177 data, a number of new coronal hole observations have been organized by Young & Muglach and these are presented here.
Seven repeats of the study 'eis_swap_ar' were run from 09:45 to
14:41 UT. One EIS jet is seen, and there is a nice plume within the
This observation used the study designed by Peter Young
('issi_jet_1') but was actually organized as part of HOP 217. The
pointing was a small on-disk coronal hole near an active region. The
most interesting thing in the data-set is the emergence of a bright
point during the 1.3 day duration of the observation.
Six repeats of the study 'issi_jet_1' were run from 18:36 to 04:10,
followed by a single run of 'GDZ_300x384_S2S3_40s'. The latter is a
larger format raster that takes more emission lines. The target was an
isolated, low-latitude coronal hole.
A coordinated observation of a bright point within a coronal hole was obtained between 10 and 18 UT on 21 December 2013. All three Hinode instruments participated as well as IRIS.
A coordinated observation of the north pole coronal hole was scheduled between 18:00 Jan-10 and 06:00 Jan-11. The Hinode plan had to be loaded three days in advance so a large format raster was scheduled. For IRIS however, I recommended a specific bright point to observe using the same study used on 21-Dec-2013.
This was run during the Hinode Christmas period plan. The south coronal hole was monitored for almost 2 days.
