Yannick opened the meeting with no announcements and moved on to the general updates from the CSDA teams

At the end of the meeting Yannick made an announcement that the JCSDA Science Workshop will take place next week (May 16 - May 18) in Boulder, and because of this we will not have the weekly (special topics) meeting next Thursday (May 18).
