Comet SWAN25F was discovered on March 29, 2025, by amateur astronomer Michael Mattiazzo using data from the SOHO spacecraft. Official confirmation and designation followed shortly after, with initial observations noted by the Minor Planet Center and other astronomical bodies.<\/p>\n

The comet\u2019s green coma, caused by diatomic carbon, is currently visible through small telescopes and binoculars.<\/p>\n

As of April 6, the comet\u2019s brightness is between magnitude 8.0 and 8.4, requiring binoculars or telescopes for observation. It is located in the constellation Pegasus, low on the east-northeastern horizon before sunrise.<\/p>\n

The comet is expected to reach perihelion on May 1, 2025, at a distance of 0.33 AU from the Sun. Its brightness may peak at magnitude 4 or 5, which could make it visible without optical aid, depending on whether it survives the solar encounter.<\/p>\n

New Comet Alert: SWAN25F \u2604\ufe0f<\/p>\n

A brand new comet \u2014 provisionally named SWAN25F \u2014 has just been discovered, and it could become binocular-bright soon!<\/p>\n

Observations indicate a tail over 2 degrees long, with visible jets and breaks pointing to active outgassing. Images captured from Arizona, Austria, and the United Arab Emirates illustrate its visibility across various locations.<\/p>\n

The comet has brightened from magnitude 10.6 on April 3 to 8.0 by April 6. Despite this rapid increase, astronomers note that the comet\u2019s survival after perihelion is not guaranteed.<\/p>\n

The comet is currently best viewed in the morning sky, with a notable alignment near the star Alpheratz expected around April 13. Observers are advised to use binoculars for better visibility.<\/p>\n

If it survives perihelion, Comet SWAN25F may be visible during sunset in early May. Its visibility will depend on how well it withstands solar heat and stress.<\/p>\n

The “SWAN”
A NEW COMET DISCOVERY<\/p>\n

Amateur astronomers are monitoring a bright new comet easily detectable by backyard telescopes. Introducing, Comet SWAN25F:

The discovery has drawn attention from amateur astronomers, including Al-Khatim Observatory in Abu Dhabi who contributed to tracking efforts, marking a milestone for regional astronomy.<\/p>\n

Although the comet could reach brightness levels comparable to stars, the possibility of disintegration remains. Continued observation will determine its potential visibility to the naked eye.<\/p>\n
