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://www.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.
