Amazing results of the Canadian team at the first GeCAA

Due to the COVID-19 pandemic, it was not recommended to host the International Olympiad in Astronomy and Astrophysics (IOAA) in any host country this year. Thus, the 14th IOAA 2020 has been canceled.

As a technical organizer, the Estonian Astronomy Olympiad Committee was responsible for all the logistics and technological solutions to make this event a success.
