Description:
Request to SOT HOP Number 0206 ???EBFI G-band: FoV 221"x111", Binning: 2x2, Time resolution: 30 min, JPEG Quality: Q75, Data rate: 9 Mbits/h ???E SP FoV 320???h x 164???h, Pixel size: 0.32???h/pix, Binning: 2x2, Single side mode Exposure: 4.8 sec (6 Cycles), JPEG Quality: Q75, Data rate: 600Mbits/map Note: margin factor FG 0x41c --- 1.3 SP 0x0c5 --- 1.3 Other Instruments: Scientific Objectives: 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.
