Remarks: |
The images above were all taken just under four weeks after the comet's perihelion, meaning it was visible in the evening sky at twilight before it set. Because of its orbit, the comet was able to be observed from both the southern and northern hemispheres. The series of images shows the
development of the comet over several days. The expansion of the opposite
tail, which was still quite narrow on 16.10.2024 and fanned out as it
progressed, is striking. A shot taken well before the closest point to the Sun can be found here. |
Bemerkungen: |
Die Bilder oben entstanden allesamt kanpp vier Wochen nach dem Perihel des Kometen, er war also am Abendhimmel in der Dämmerung zu sehen, bevor er unterging. Aufgrund seiner Bahn war es möglich, den Kometen sowohl von der Süd- als auch von der Nordhalbkugel zu beobachten. Die Bilderserie zeigt die Entwicklung des Kometen über
mehrere Tage. Auffällig ist die Ausdehnung des Gegenschweifs, der am
16.10.2024 noch recht schmal war, und im weiteren Verlauf aufgefächert
wurde. Eine Aufnahme deutlich vor dem sonnennächsten Punkt ist hier zu finden. |
