A Rare View of the Green Laser Scan from the Space 2023-1-28 UT
from 管理人_SubaruTel_StarCamAdmin, Jan 28, 2023
Last night (early morning 2023-1-28 HST) was cloudy on Maunakea. But our Subaru-Asahi Star Camera captured quite an interesting view -- green laser lights coming from the sky!
It was only a second or less -- but our keen viewers did not miss the event!
That was so a mysterious view, then later the viewers got a conclusion from the information on the net -- it could be a remote-sensing laser (altimeter called ATLAS) from ICESat-2/43613 (BUT see below: different conclusion emerged!)!
What great people! We really appreciate their great contribution to catching such a rare view!
** Correction 2023-02-06 ! ***
According to Dr. Martino, Anthony J., a NASA scientist working on ICESat-2 ATLAS, it is not by their instrument but by others.
His colleagues, Dr. Alvaro Ivanoff et al., did a simulation of the trajectory of satellites that have a similar instrument and found a most likely candidate as the ACDL instrument by the Chinese Daqi-1/AEMS satellite.
We really appreciate their efforts in the identification of the light. We are sorry about our confusion related to this event and its potential impact on the ICESat-2 team.
