The Chandra schedule

3-day Schedule

The map of the observations requires JavaScript, but it appears that it is not available (or the page is taking some time to load).

This page shows 3 days of the Chandra schedule, either side of today, and the total science exposure time for these observations is 4 days and 18 hours. The size of the circles indicate the exposure time, and the color shows whether the observation has been done, is running now, or is in the future; the same colors are used in the table below. For repeated observations it can be hard to make out what is going on, since the circles overlap! The shaded regions trace the Milky Way galaxy. The points are plotted in the Equatorial coordinate system, using the Aitoff projection.
