Comet Tsuchinshan-ATLAS Comes into View of Coronagraph Imagery

Comet Tsuchinshan-ATLAS Comes into View of Coronagraph Imagery
Comet Tsuchinshan-ATLAS Comes into View of Coronagraph Imagery
published: Tuesday, October 15, 2024 15:39 UTC

Comet C/2023 A3 (Tsuchinshan-ATLAS) came into view of the NASA/SOHO Coronagraph on 7 October. The comet's appearance coincided with an X2.1 (R3-Strong) flare and a pair of coronal mass ejections (CME). The comet will continue to pass from the right to the top left of the Sun into October 10th before it moves out of view by October 11th. During its transit across the coronagraph imager, it will continue to be a magnificent presence, but could over-saturate imagery due to its tremendous brightness.
