We have added two new Observing Challenge Certificates: TESS and Mars InSight.  These activities have deadlines in 2018.  For more information, checkout the webpage:  https://test.astroleague.org//programs/nasa-observing-challenges-special-awards-introduction

​You do NOT need to be a member of the Astronomical League to participate in these Observing Challenges.  Certificates will be awarded, but there are no lapel pins.
