✧ C/2022 E3 (ZTF) ✧
C/2022 E3 (ZTF) is a non-periodic comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) in 2022. With a comet nucleus of around 1 kilometre (0.62 mi) in diameter, C/2022 E3 rotates on its axis once every 8.5 to 8.7 hours. Its tails of dust and gas extended for millions of kilometers and, during January 2023, an an...

Как Яндекс помогает астрофизикам изучать вспышки на красных карликах
Красные карлики — наиболее распространённый тип звёзд в нашей Галактике. Это не самые яркие объекты: они меньше нашего Солнца и светят слабее. Однако большинство планетных систем обнаружено именно вокруг звёзд этого класса. Благодаря многолетним исследованиям у астрофизиков накопилось множество данных о поведении красных карликов. Каталоги современных обзоров неба содержат десятки миллиардов отдельных наблюдений для сотен миллионов таких звёзд. Традиционные методы обработки данных больше не справляются с такими объёмами, поэтому для их анализа учёные все чаще используют методы машинного обучения. В этом году мы запустили совместный проект со специалистами Государственного астрономического института имени П. К. Штернберга МГУ, Факультета Космических Исследований МГУ и Университета Карнеги‑Меллона, которые работают в международной команде SNAD . Центр технологий для общества Yandex Cloud помог учёным выстроить пайплайн машинного обучения для поиска звёздных вспышек с помощью облачного сервиса Yandex DataSphere и в итоге создать самую крупную выборку вспышек на красных карликах по данным наземных наблюдений. Совместно с исследователями Анастасией Лаврухиной, Борисом Демковым, Константином Маланчевым @hombit и Марией Пружинской расскажем, как именно машинное обучение помогает астрофизикам, и какие новые научные прорывы это может обещать.

This evening #comet C/2023 E3 (#ZTF) was even harder to detect with my super-simple equipment than yesterday ... but it is again, marked in the best single frame - 1.3 seconds at f/2.8 and ISO 6400 with maximum zoom - I got out of the Moon- and city-brightened sky. Could well be the last image for me ...

Yay, got #comet C/2023 E3 (#ZTF), now down to 8-9 mag., one more time with the DMC-FZ300 on a tripod, at maximum zoom and ISO 6400 and even 3200 - short exposures were necessary due to its low decination = high angular speed in the sky. And the moonlight also didn't help but still: here - following some robust gamma increases - it clearly is! So long, on your way out of the solar system.

A little late to the “Green Comet” party as I've been learning how to capture and process comets for the first time, and it's been a fun effort. Check out my capture of C/2022 E3 (ZTF) including 15 minutes of integration time for each of RGB channels. The image was captured on February 11th, and more detail can be found here: https://wp.me/p2dYHY-1FW.

The 'performance' of comet C/2023 E3 (#ZTF) discussed in detail in http://fg-kometen.vdsastro.de/koj_2022/c2022e3/22e3eaus.htm - the peak magnitude near perigee near 4.9 *was* what was widely predicted in the days after its discovery, by the way.

C/2022 E3 (ZTF)
C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on March 2, 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. It’s closest approach to Earth was on February 1, 2023, at a distance of 0.28 AU (42 million km; 26 million mi).

The Japanese #EQUULEUS spacecraft - launched with #ArtemisI - has successfully photographed comet C/2022 E3 (#ZTF) from space! EQUULEUS is sailing toward the Lunar Lagrange point, and these series of images were taken by calculating the timing and direction from the relative orbits of the comet and EQUULEUS: https://twitter.com/EQUULEUS_en/status/1627864630419931137

Mijn laatste foto van #komeet C/2023 E# #ZTF, gisteravond gemaakt met een stilstaande camera. De komeet is het wazige groene spoor in het midden. Laatste foto, want de komeet wordt snel lichtzwakker en met een omlooptijd van 50.000 jaar was hij letterlijk een once-in-a-lifetime gebeurtenis. De heldere ster rechtsonder is Aldebaran in sterrenbeeld Stier. Laatste ook, want voorlopig is het 's avonds weer bewolkt.

Another very clear evening in #Bochum, Germany ... and so here is #ZTF again, close to a 9.75 mag. star and near #Aldebaran and the #Hyades: all images with a Panasonic #Lumix DMC-FZ300 at f/2.8 and various zoom settings (35 mm equivalent focal lengths given; images cropped moderately) - some more pictures are also in https://www.facebook.com/dan.fischer.393/posts/pfbid0QviziYzpAr7KTrEenTFVBAjNRocgmVv9Ge6k4D91jdmEgrtFYUK3qbDqg8LdH3akl

#astronomy #comet #ztf
okay okay okay... i did it... i finally imaged comet ZTF 🤷don't get distracted by this RGB stars - the comet is very very quick moving and if you have a monochrome camera, you have to decide what you want colored. the stars or the comet 🙂

Faded comet #ZTF visiting the open star cluster NGC 1647 and approaching the Hyades cluster on the evening of 13 February 2023: images from Bochum, Germany, with a Panasonic DMC-FZ300 on a tripod, on lhe left at 2 seconds at f/2.8 and ISO 6400, max. zoom & cropped a bit, on the right 5 seconds at f/2.8 and ISO 3200. In 11x70 binoculars both the comet - approaching 7.0 mag. now - and NGC 1647 were just at the limit of visibility with averted vision in the given very clear but also (sub)urban sky.
