# National/ International Astronomy Olympiad Problem Sheets

[Updated: 2 July 2020]

I have some of the files, but I think it’d be easier to link to their pages as well (so that if anyone asks me I can just link him/ her this). Basically, you can just go to their own respective websites, but having them in one place helps a lot (especially for my Indonesian students/ friends). I try to link to official websites if I can. If I don’t have the links but I have the files, will upload them.

(Still building sources from dusty folders)

## OSN Astronomi (*Olimpiade Sains Nasional*/ Indonesian National Olympiad) (in Bahasa Indonesia)
