** Established in Thailand 2006, it was initiated by five countries including Thailand, Indonesia, Iran, China and Poland with the aim to proliferate Astronomy among high school students, to foster friendship among young astronomers at international level so as to build cooperation in the field of Astronomy in the future among the young scholars
Observational Examination
questions concerning direct observation of the sky (in the real sky or in a planetarium), recognizing stars, constellations, nebulae, great circles, etc. It counts as 25% of the mark.
Observational Examination Night
Instructions :
1. Do not open the exam envelop yourself.
2. This part of the exam involves observation with real sky. You must complete two tasks using the equipment provided.
3. Hand the exam envelope to the proctor at the exam station.
4. You have 6 minutes to complete the first task, and 4 minutes to complete the second task.
5. Once you complete a task, call out to the proctor to have it graded.
6. Once graded, that answer is considered final and you may not return to it again.
7. Once the timer has expired any ungraded task will be graded as is. (So make sure you complete the task before the timer has elapsed)
N1: Observation with Equatorial Mount Telescope
Instruction: Use the Equatorial Mount Telescope to observe the target given in the star chart. Write down the Name and make sure the target is focused.
Included :
**Equatorial Mount Telescope
**Mount is already polar aligned
**Eyepiece: 25 mm
**Finder scope already aligned with the main scope
**Telescope starts already pointing at “starting star” (see map)
**Star chart with starting and target position marked
N2: Observation with Dobsonian Telescope
Instruction: Use the Dobsonian Telescope provided to observe only one of the following objects and focus on selected object.
Included:
**Dobsonian Telescope
**Eyepiece: 12 and 25 mm
**Finder scope is already aligned with main scope.
Observational Examination Day
Instructions :
1. Do not open the exam envelop yourself.
2. This part of the exam consists of 7* problems located in separate exam stations.
3. You have 5 minutes to complete each problem.
4. After “out of time” is signaled, stop all actions and remain at the same station.
5. After “next station” is signaled, proceed to the next exam station and hand the exam envelope to the station’s proctor.
6. Use only blue pen to mark into the answer sheets provided. Any answers written in the answer sheet at the end of timer is considered final and will be graded towards the final score.
P1: Naked eye observation from real sky with panoramic 360-degrees image
Instruction: Estimate the LST (Local Sidereal Time) at the time the image was taken, rounded to nearest hour
Included :
**Panoramic 360-degrees image of the sky at night at an unknown location
**Computer screen
**Keypad to pan around the image
**Coordinates of bright stars
P2: Planet observation with real sky in panoramic 360**degrees image
Instruction: Count the number of planets visible in this image above the horizon and name the constellations they’re in (with IAU designations).
Included :
**A panoramic 360-degrees image of the sky at night at an unknown location
**Computer screen
**Keypad to pan around the image
P3: Analemma on another planet
Instruction: Find the Obliquity (Axial Tilt) of the planet
Included:
** A generated analemma (position of a Star taken from the surface of a planet with interval separated by mean solar day of the planet over an orbital period around a Star) of a fictitious planet orbiting around a Star.
** Result is graphed on a paper with each major grid representing 5°
