Due to problems that occurred when we sent out the AC invitations, we have extended the registration deadline to May 23rd. We apologize for any inconvenience caused.
Please also note that there have been slight modifications to the syllabus this year. Interested parties should check out the updated syllabus here. The syllabus and other pertinent information can also be found in the “More Information on AstroChallenge” tab.
Lastly, we will be issuing a more comprehensive formula list this year. This formula list will be uploaded on the website in short order (along with the information letter).
