Although the comet won’t be closest to Earth until February 1st, it’s best seen for now because the moonlight is still barely visible. To get a clear view of the night sky, you have to make your way through the high fog.

Comet C/2022 E3 ZTF?

The comet was discovered on March 2, 2022 by the “Zwicky Transient Facility”, hence the acronym “ZTF”. The last time a comet approached Earth was 50,000 years ago, during the Neanderthal era. The comet, with a diameter of one kilometer, is approaching Earth again: it was at its smallest distance on February 1, 2023 at 42 million km. C / 2022 E3 ZTF consists of snow and dust. The tail appears greenish, indicative of a dust tail.

When can a comet be seen?

Without the disturbance of moonlight, the ideal observing date was last weekend. The Cantonese School in Heerbrugg / SG managed to get a registration last night. Observations are still possible on the coming nights, even if the moon becomes increasingly noticeable. You do need good binoculars though. More information and a map of the location is available at Starry Sky here to exist.

Where does the comet appear from?

In the lowlands and in the foothills of the Alps, the view of the sky will be obscured by the high mists of the coming nights. Also in the south there are fields of high fog and sometimes clouds. Places above the Sea of ​​Fog on the northern slopes of the Alps or inland alpine regions are ideal. The upper limit of high fog is currently 1,200 to 1,500 meters, and this limit will increase on Thursday.

If you can get a picture of the comet, we’ll be very happy: #SRMFeteoImage
