Timeline for XL-CALIBUR

The following is the timeline for the XL-CALIBUR mission. The table includes the time of the event, the observation ID if available, and a small descriptiton of the event. If data is available, the hyperlinks on the observation IDs will take you to the XL-CALIBUR archive directory for that observation.
