A Rare View of the Green Laser Scan from the Space 2023-1-28 UT / 稀な宇宙からのレーザースキャンシーンを捉えた！}

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.
