Planisphere
As an Indonesian, I was really not grateful (hmm, maybe not me) enough that I am able to be a viewer of the whole, both sides of the sky, able to see both Crux and Ursa Mayor, sure truly a blessing, for the whole year.

Most of these (okay, maybe no Polaris for me) (astroplot.com)
Perseid, with Nice Maps
I don’t know why, seems like my writings lately are mostly about maps? I wonder… Anyway, tonight and yesterday night were the peak of Perseid Meteor Shower this year (mostly yesterday, but today should be quite fine). As I live far from civilisation the city this year, the result of the quick sighting I’d done last night was quite nice. Though I didn’t venture far from the flat, I could see a lot of shooting stars (basically the shower part) coming from the east (where Perseid was located these time of the year before the dawn), and I believe there’s a fireball too!
With this infographic, I have benefits of not needing to write about the meteor shower and not needing to write a lot as this article seemed long enough already
National/ International Astronomy Olympiad Problem Sheets
[Updated: 16 September 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.

A must read

Designing Mission Patches
As I was looking for outreach activity to do, I encounter designing space mission badges/ patches. Space mission badges is usually designed to be worn on an astronauts’ suit. They usually have the austronauts’ names, the space shuttle, symbol/ logo about the mission, and flags of the country/ies involved.
These are from all the Space Transportation System (STS) a. k. a. Space Shuttle missions
