The duration of night-time is calculated for the visible band, and in the peak of eclipse season (around mid-July [3]) this duration is about 20 minutes. EUV absorption (night ingress) begins about 10 minutes before the calculated entry into optical night (listed as NGT_ENTRY) and ends (night egress) in the EUV about 10 minutes after the optical band exit (NGT_EXIT). Thus, the EIS operations team recommend that you leave a __ten-minute buffer around s/c night__ in eclipse season where possible. Extended-duration observations
As of 2009, JAXA ephemeris calculations for Hinode included the calculation of nominal EUV and X-ray night (known as XTW). The duration of these is approximately 30 minutes at the peak of eclipse season (2009). This is calculated from a static model, and so doesn't take into account expansion of the ionosphere with increased solar activity, which would lengthen these obscuration periods.
At line 31 changed one line
At the middle of eclipse season, clear EUV day (i.e., not including transition into or out of eclipse) lasts for approximately 60 minutes (not taking into account expansion of the ionosphere with increased solar activity).
