    Comet F3 NEO Wise

    Comet F3 has entered the Lasco 3 instrument of SOHO and will be visible for several days. Go here and download your own movie.

    spaceweather.com also has the video if you don't want to download your own.

    "Comet NEOWISE has been rapidly brightening since entering the coronagraph's field of view on June 23rd," reports Qicheng Zhang, a PhD candidate in planetary sciences at Caltech. "It's jumped from magnitude +4.0 to +2.9."

    If this trend continues, Comet NEOWISE will be easy to see with the unaided eye when it emerges from the sun's glare in mid-July. First, though, it has to survive the sun.

    Comet NEOWISE reaches perihelion (closest approach to the sun) near the orbit of Mercury on July 3rd. SOHO will be able to follow the comet to the doorstep of that encounter. If NEOWISE it is still intact on June 28th when it leaves the coronagraph's field of view, there's a good chance it will "go the distance" and become a summer comet of first magnitude. Stay tuned!
    Hopefully it survives its close approach to the sun. If it does, it may be an very good naked-eye comet.

    So far there are some very good images being taken around the world when the comet was visible in the morning. Hopefully it's just as bright in the evening over the next week or so.

    Cool NEOWISE Graphics

    I've created two charts and an ephemeris for Comet C/2020 F3 NEOWISE: https://www.curtrenz.com/comets.html

    I saw it last night- it was great! The most comety comet I've managed to see. Not as bright as Hale-Bopp (yet) but a long tail, pointing straight at the Sun.
    Unfortunately it is in the North, which is the brightest part of the sky this time of year, but I could see it easily at 02.30 in the morning. Averted vision was best.

    I’m curious but what is your latitude? I would think NEOWISE would be below the horizon at that time.

    Here's the map I was using, from the BBC. The comet is to the west of Capella.

    I've now created two additional charts to display the Comet relative to the horizon before sunrise and after sunset.

    Forum member Paramount has taken this movie from about 20 miles from where I live. This is what we saw last night.

    Trying to figure out how to square the predawn appearances with the need to wake up at 7:30 for work and get to bed 8 hours before that.

    I'm thinking an early-to-bed strategy might work.

    Saw it again, last night, despite intermittent cloud. Due north, this time, at about quarter to one in the morning. As I suspected, it is circumpolar here.

    Curt, thanks for the charts. I just now had a fine evening view, despite twilight and severe light pollution. With my 15x50 image-stabilized binocularsI could see about a degree of the tail streaming from a bright, condensed inner coma. It is still an easy naked eye object.

    I tried last night with no luck; if I was looking in the right spot (and I could see the Dipper, so I think I was close), there were clouds where the comet should be. I'll try again tonight. Did have a nice ISS pass to watch.

    Tried again last night and still no luck. No clouds, maybe just too much light pollution.

    For this to be such a bright, impressive comet, it has been frustratingly illusive.

    Saw it last night at first out the bathroom window then went into the backfield to see it, the house blocks the dusk to dawn light in out driveway. Tonight unfortunately it is cloudy out.

    It just doesn't seem to have been dark enough when I go to bed, usually about 10:20. But I'm old and need my sleep. If it's clear tonight maybe I'll try staying up for a while.

    Finally saw it tonight. About +3.5 magnitude. Beautiful against a dark blue sky. Reminded me of Hale-Bopp.

    No blasted clouds here!
    So I stayed up late. I went up on the upper deck, where it's darker. I sat down and closed my eyes to adjust them to the dark. Opened them up and Wow! Why is it so hard to see across the street?


    Fog. Blasted fog.

    Oh well.

    While we're admiring the view, there is science going on.
