The eclipses have their maximum duration around 20 June each year. The EIS CO is provided with the times for "X-ray twilight" each orbit and, for 20 June 2009, the duration of XRT twilight was 30 minutes. The guideline for EIS COs is to schedule the next observation no less than 2 minutes after exiting XRT twilight. (N.B. This is now factored into the planning tool buffers which allow observing windows to be calculated).
