!XRT Synoptic Re-pointings
One caveat to the above information on observing windows is that (currently) twice a day, Hinode's X-Ray Telescope (''XRT'') makes a so-called synoptic observation of the Sun. This requires the satellite to point at solar disc centre. However, because XRT is sensitive to particle radiation, and X-ray nights are almost equivalent to EUV nights, it requires these observations to be taken during one of the clear observing windows (above). The duration of XRT's programme (including the time taken to re-point) is 10 minutes. Factoring in the 2 minutes post-pointing delay after the synoptic, this means that observing windows (typically, those closest to or including 06:00 and 18:00 UT) are curtailed by 12 minutes.
