Comet C/2023 A3 Tsuchinshan-ATLAS: an image – 14 May 2023

Comet C/2023 A3 Tsuchinshan-ATLAS will hopefully be bright enough to put on a nice show late next year. While waiting and hoping, we imaged it last night.

Comet C/2023 A3 Tsuchinshan-ATLAS: 14 May 2023.

The image above comes from the average of four, 120-second exposures, unfiltered, remotely taken with the Celestron C14+Paramount ME+SBIG ST8-XME robotic unit available as part of the Virtual Telescope Project. We have been waiting for weeks for a clear night to capture this icy world. In the image above it looks stellar and we measured it as bright as mag. 16 (unfiltered, R-mags for the reference stars from the Gaia DR2 star catalogue).

Comet C/2023 A3 was discovered on 9 Jan. 2023. Since it was announced, it was clear that this icy world might reach naked eye visibility late in Sept. 2024, with chances to be remarkable.

We will keep an eye and it and will schedule a live feed in due time.
