MSE again enjoyed a strong presence at the 2020 AAS Winter Meeting in Honolulu.  MSE held a special session featuring talks by each of the Science Working Groups; these talks are posted on the wiki: https://redmine-mse.cfht.hawaii.edu/projects/science/wiki/aas2020 .  MSE also held a reception to bring together interested parties that was very well attended, and MSE and CFHT hosted a booth in the Exhibit Hall which was visited by hundreds of meeting attendees.
