There's a new comet in the sky, and it's already visible through binoculars | CBC News
One of the great things about astronomy is that it’s always full of surprises, especially when it comes to comets — you just can’t predict new ones. But there’s a lot of buzz around a recently discovered comet that has quickly brightened.

Planetarium BochumDer bisher notdürftig als #SWAN25F geführte Komet - hier gestern früh von Christoph Gerhard: https://www.facebook.com/photo/?fbid=9616963628419224 - hat in http://www.cbat.eps.harvard.edu/iau/cbet/005500/CBET005538.txt endlich eine offizielle Bezeichnung erhalten, die zufälligerweise recht ähnlich ist: C/2025 F2 (SWAN). Der Sonne am nächsten kommt er am 1. Mai in 1/3 Astronomischer Einheit Abstand: Dann sollte er auch sein Helligkeitsmaximum erreichen, vielleicht 3.6 mag. - aber das ist sehr unsicher wegen der konfusen Lichtkurve bisher. Und nur 19° Elongation.
Daniel FischerAnd so the comet formerly known as #SWAN25F has finally received an official designation: C/2025 F2 (SWAN). The respective CBET http://www.cbat.eps.harvard.edu/iau/cbet/005500/CBET005538.txt is just out: perihelion will be on 1 May at 1/3 au, coinciding with a predicted peak magnitude of 3.6 - albeit at an elongation of only 19° and "highly uncertain" as the brightness behavior so far isn't well understood and "[o]bservers have commented on a clear outburst in brightness having occurred around April 5."

Comet SWAN25F: an image – 8 Apr. 2025
Jorma RyskeHere #comet #SWAN25F images taken today early morning 8th April from my remote observatory at Spain. SWAN25F is quite low in the morning sky near Pegasus square upper area between stars Alpheratz and Scheat. It's magnitude is about 9, tail visible almost one degree toward PA 300deg and coma diameter is 5'. Animation 18x30sec in the link below shows also moving tail details.
