 abstract of observational proposal
The data obtained by the HOP81 observations show that the longitudinal dependence of polar reversal is large. Especially, the dependence becomes important for understanding the progress of polar reversal when polar reversal is progressing to the final phase. Hence, we propose the special observation for taking the panorama map of magnetic field around Pole. If we want to make the panorama map that covers until 65 degrees latitude, we need to perform the polar observation every 3.5 days during one month. Considering the matters about Hinode operation (flares, satellite operation, etc.), we request to perform the polar observation every 3 days. It means that we need to perform 10 polar observations for one panorama map during one month.

 request to EIS
EIS Study ID: 304 SK_CH_DIAG_320x284

This study performes a large scan for coronal holes with low temperature lines (log T < 6.2). It is designed for polar monitoring campaign with SOT/SP measurement of magnetic fields.

-------------------------------
[Target of HOP206]
March: Only South Pole
September : Only North Pole
--------------------------------
Pointing: [0, 900] (for North Pole), [0,-920] (for South Pole)
  >>When CP fixs the coordinates of the pointing for HOP81,
      CP must apply the SOT-UFSS offset to the coordinates.<<
Frequency: One observation per 3 days.
Period: 30 days (10 Observations)
Period for one observation: 6 hours (Time for twice polar scans of SOT-SP)

[Guideline about postponing] (edited on 2015.04.02)
The guideline about postponing HOPs during a Major Flare Watch was written before HOP 206 came along.  This HOP is unique in that it requires observations every 2 or 3 (or maybe 4) days for a month to capture the polar fields, and the chance comes only in March and September.  The guideline says synoptic HOPs may be delayed up to 3 days; but HOP 206 by its nature has a maximum delay of 3 days (maybe 4).  The tradeoff is between missing a possible large flare in a 7-hour period, versus causing a significant gap in an observation that takes a month to do. Therefore, the CP & COs are urged not to allow gaps of more than 4 days in a sequence of HOP 206 runs, even if there is a Major Flare Watch.
