Science Goal: CORE: SOT continuous magnetic field observations for investigating mechanisms responsible for XBPs and QS dynamics
Program: Full_Sun_Movie_with_Ti/Poly_19

Instrument: XRT
HOP/JOP: 0
Description:
Daily Note: ***** OP START after KRN1 ***** ***** Hinode observations are idle in the period between Dec30 and Jan 4 because of no commanding operations ***** The last day for command uplinks before the new year holidays. The OP needs to cover the final plan until Jan 4 (plus backup plan). 4 commanding paaaes are scheduled for ensuring the completion of the preparation for the new-year-holiday operation. Dec 29 (Sat) at 01:30UT (10:30JST) --> daily meeting (to decide 4-day upload) Dec 29 (Sat) at 07:05UT (16:05JST) --> OP upload for one day Dec 30 (Sun) at 01:30UT (10:30JST) --> special daily meeting for Jan 4th upload Dec 30 (Sun) at 07:24UT (16:24JST) --> OP upload for four days Jan 4 (Fri) at 01:30UT (10:30JST) --> first daily meeting of the year Jan 4 (Fri) at xx:xxUT (yy:yyJST) --> first OP upload for one day

Scientific Objectives: Previous magnetic-field observations (/w 1-2 arcsec spatial resolution, longitudinal only) shows that magnetic cancellation is involved in many XBPs and magnetic emergence in a limited number of XBPs (e.g., Harvey et al.) Priest and Parnell (1994) proposed a magnetic canceling model for explaining the overall evolution of XBPs. However, this model has not yet been confirmed with observations. SOT has not yet performed magnetic-field observations suitable for investigating mechanisms responsible for XBPs (see Kotoku et al. 2007 PASJ). The biggest problem in the observations made so far with Hinode is that continuous SOT observations are available only in a few - several hours, which is much shorter than the lifetime of XBPs (8 hrs for small typical XBPs, 48hrs for bigger XBPs) and time-scale of small-scale magnetic field evolution (Schrijver et al. 1998). We are lack of observations with continuous a-few days tracking of a quiet region with Hinode SOT coodinated with XRT and EIS.
