La comète ZTF « presque » au plus près de la Terre !

Link: https://flic.kr/p/2ofRj56

Le dimanche 29 janvier 2023, le beau temps s’invitait enfin en Gironde. La comète C/2022 E3 (ZTF) n’était plus qu’à 3 jours de son approche au plus près de la Terre alors qu’elle filait à toute vitesse vers les confins de notre système solaire d’où elle était sûrement issue.J’ai donc installé mon setup grand champ dans le jardin situé au milieu du village d’Ayguemorte-les-Graves baignant dans la pollution lumineuse. Heureusement, la comète se situait assez haut, tout près de la constellation de la Petite Ourse, remontant vers Polaris, l’étoile polaire. Petit rappel : cette comète est déjà venue visiter la planète Terre mais à une époque où l’Homme moderne n’était encore qu’un chasseur-cueilleur, soit 50.000 ans environ. Provenant vraisemblablement du nuage de Oort, elle a été découverte le 2 mars 2022 par le programme de relevé astronomique « ZTF » (Zwicky Transient Facility) qui utilise le télescope de l’observatoire Palomar. C/2022 E3 accuse un diamètre d’environ 1 km. La lueur verte est sa coma (chevelure) est due au carbone diatomique (C2) incandescent. Photos prises dans la nuit du 29 au 30 janvier 2023 à Ayguemorte-les-Graves (33) – Canon 40D défiltré partiel avec objectif Sigma 70-300, focale à 238 mm, ouvert à 5,6, sur monture StarAdventurer (sans goto ni autoguidage). 426 poses de 60 s – ISO 800 – 25 DOF – Iris, VirtualDub et Toshop.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
