Observe Sky Objects: NARIT’s Classification Method

Summary of Sky Object Identification Guide by Dr. Matiphon Tangmatitham

This article by Dr. Matiphon Tangmatitham from the National Astronomical Research Institute (NARIT) provides a guide to identifying common sky objects and avoiding misidentification, particularly wiht things like drones or unidentified phenomena. Here’s a breakdown of the key information:

1. Common Misconceptions:

* Manny reported sightings are simply misidentified regular lights – planets, stars, streetlights.
* Human eye movement (rolling, head movement) and camera shake can create the illusion of movement in stationary lights.
* Improper camera settings can distort brightness and clarity.
* Venus is frequently mistaken for something unusual due to its brightness and distance from the sun.
* Radiant stars in constellations are more visible in clear winter skies.

2. Identifying Different Objects:

* Planets & Stars:

* Observation: Fairly constant light, doesn’t move relative to ground objects.
* Check: Observe surrounding stars to identify constellations, or use a stargazing app.
* Satellites:

* Observation: Relatively constant light, moves slowly in one direction. frequently enough visible after sunset or before sunrise. May flash briefly as solar panels reflect sunlight.
* Check: Moves in a straight line, faster than an airplane.
* Note: Large satellites like the ISS or Tiangong can be very bright.
* Meteors:

* observation: Bright, flared spots that appear for a fraction of a second (tho fireballs can last longer).
* Check: Travel in a straight line, faster than airplanes and satellites.
* Note: Around 17 meteors large enough to be visible reach Earth daily, with more frequent sightings during meteor showers.

In essence, the article encourages careful observation and understanding of how these objects actually behave to avoid jumping to conclusions. It emphasizes that many “mysterious” sightings have perfectly natural explanations.
