HOP 59 - Quiet Sun Evolution - A Hinode Heritage Study
The plan for this HOP was to track the quiet Sun continuously
near disk center for three days. EIS would take 50% of the data
recorder allocation rather than the usual 23% in order to allow a large
field-of-view and a wide wavelength selection.
22-25 January 2008
This was scheduled during the period Hinode was having
problems with the X-band antenna (which eventually failed). This meant
the satellite data rate was lower than originally expected.
Due to the lower data rate the original HOP 59 study was
swapped for the study cam_qs_2as_context, which covered the area 120" x
360" with the 2" slit in 33 minutes. Rather than run continuously, the
study was scheduled at approximately 50 minute intervals from 11:12 UT
on 22 January to the final raster beginning 09:06 UT on 25 January.
Of the 81 total rasters, eight were lost due to telemetry problems. The longest gaps were from 22:13 (23rd) to 00:10 (24th), 09:03 to 13:15 (24th), and 15:20 to 17:05 (24th).
I fit single Gaussians to Fe XII 195 and He II 256, and I show
below the movies derived from the fit parameters.
