March 18th 2019: TNO 38628 Huya occults 11th magnitude Star TYC 5061-513-1
A very rare and interesting event happened on March 18th 2019: a recently discovered and rather “enigmatic” large trans-neptunian celestial body located at an enormous distance (approximately 30 AU from the Sun) passed right in front of a relatively bright star in the Ophiuchus constellation, as viewed from observers located in Eastern Europe (see the maps with the occultation path projection for details)!
An observation campaign was proposed and coordinated by the professional astronomers Pablo Santos Sanz and Marcel Popescu, and many amateur astronomers joined in to provide useful scientific data!
Here you can see the maps with the occultation path prediction (the green line is the center of the path):
As Star Dreams Observatory was on the visibility path, I easily joined the observation campaign and enjoyed it!
Below is an animation of the captured images of the event (at a rate of 5 frames per second, UT stamp), with the star in the center disappearing while the TNO crosses in front of it, from my perspective:
Equipment used: RC 200 with ASI120MM-S camera
