We have been passably favorable with comet in the last several months . We hadComet Tsuchinshan - ATLASlast October shining across the sky for weeks , seeable to the naked heart , having hold out a dangerous close confrontation with the Sun . That prospect now lies with C/2025 F2 ( Swan ) , although it ’s not expected to get as bright .

The comet wasdiscoveredby three citizen scientists , Vladimir Bezugly , Michael Mattiazzo , and Rob Matson , in quite an unusual way . They were not looking at the sky but at trope get by the Solar and Heliospheric Observatory . They were looking at the data from the Solar Wind Anisotropies instrument ( Swan ) , and independently , they reported the presence of the comet between March 29 and 31 .

The comet brightened middling quickly , and it now has amagnitude of +7.8 – not bright enough for our own center , but seeable with a small telescope or binoculars . But the best is yet to come , since the comet has not give its closest degree to the Sun just yet . That ’s proceed to be on May 1 , as the comet will reach just within the orbital cavity of Mercury .

Currently , the comet can be seen in the morning before aurora in an E - to - northeastern United States counsel , as well as right on after sunset , broken on the visible horizon . Over the next 10 mean solar day or so , it will get high from the visible horizon in the evening , make it easy to see at more commodious hours , which works nifty , given that it will also get brighter . Current idea advise that it might get to magnitude +5.5 , putting it in the visible to the naked eye range .

As far as astronomerscan tell , it is not estimated to get promising than that , but it might have outbursts that we ca n’t simply predict . Its current brightness evoke that this is a large comet , not at the stage of the “ megacomets ” but sure enough enough to outlive the close passing . The sizing might make it easier for non - destructive flare-up .

So far , the comet has not released much rubble . In fact , it is shining a green coloration just likeComet Nishimuraof 2023 , which was dub the “ green comet ” for just how fleeceable it was . The emerald hue is triggered by diatomic carbon , a clear sign that the comet ’s comatoseness ( the fuzzy atmosphere of the comet ) is rich in flatulence than in dust .
