CentaurZ Posted April 18, 2020 Share Posted April 18, 2020 (edited) Comet C/2020 F8 SWAN was discovered on March 25 by use of the SWAN camera aboard a European satellite. Based on JPL orbital elements, I calculate that its magnitude will peak at +8.9 on May 15. Although comet brightness predictions can vary significantly from eventual readings. Below are two charts that I created. Photos and descriptions of the comet would be welcome additions to this thread.

Owmuchonomy Posted April 19, 2020 Share Posted April 19, 2020 I was catching up on this here at breakfast: https://spaceweathergallery.com/indiv_upload.php?upload_id=161451. The suggestion in the article is that it is around mag 7 or 8? Link to comment Share on other sites More sharing options...

John Posted April 19, 2020 Share Posted April 19, 2020 c2020 F8 Swan is in Sculptor at the moment at magnitude 7.8 according to "The Sky Live": https://theskylive.com/c2020f8-info Link to comment Share on other sites More sharing options...

jonathan Posted April 24, 2020 Share Posted April 24, 2020 (edited) What instrument would you say is best under reasonably dark skies to see this comet? I have a 70mm travel scope, 70mm bins, and the others in my signature. Wanted to see ATLAS but alas things conspired against me on that one.

Davey-T Posted April 24, 2020 Share Posted April 24, 2020 (edited) Nexstar should get it if you put the co-ord's in, don't think it's visible from UK yet. Dave Edited April 24, 2020 by Davey-T Link to comment Share on other sites More sharing options...

verreli Posted April 25, 2020 Share Posted April 25, 2020 Give it a couple more weeks and it'll be visible in the UK and its magnitude should be moving into the naked eye range [usual comet caveat applied]. Link to comment Share on other sites More sharing options...
verreli Posted April 30, 2020 Share Posted April 30, 2020 Swan currently at Mag 5.5 so naked eye visible and brightening. Still not visible from the UK. Will it last until 22nd May and the new moon? Link to comment Share on other sites More sharing options...
Paul M Posted April 30, 2020 Share Posted April 30, 2020 Looks like Swan has potential May into June as a circumpolar object. A midnight spectacle? 2 Link to comment Share on other sites More sharing options...

Scosmico Posted May 2, 2020 Share Posted May 2, 2020 There is a live on youtube tomorrow 8h30 AM BST from Astroneos, Brazil. The same group who have discovered some comets and asteroids recently. Comet Jaques, 2019 OK and others. Latest reports Magnitude 5.1. Coma 10". https://youtu.be/8-xlAL7uKno Today's live is still happening. Brazilian portuguese though. But everybody speaks astronomy. 1 Link to comment Share on other sites More sharing options...
Merlin66 Posted May 2, 2020 Share Posted May 2, 2020 It seems to be putting on a reasonable show from Australia. Early morning object visible in Bino’s.... Link to comment Share on other sites More sharing options...

Craney Posted May 3, 2020 Share Posted May 3, 2020 One thing that comes around more often than a comet...... is the hope of a good comet display !! Fingers crossed for this one. 1 Link to comment Share on other sites More sharing options...

Bet you'll get a decent view from brimham rocks or Sutton bank, lock down depending 1 Link to comment Share on other sites More sharing options...

Brimham is good looking North at night for Aurora and Noctilucents because there is not much habitation thereabouts. North East should be good. Never been to Sutton Bank on a night / early morning. I wonder if it's relative altitude might open issues from York to the South. Still if the comet is 'better than average' (note suppressed enthusiasm not to tempt fate) it would be worth a trip out. Have already been in the garden mapping out where the comet will be in a month or so time. Might have to take the roof off !!!! Link to comment Share on other sites More sharing options...
Pete Presland Posted May 3, 2020 Share Posted May 3, 2020 There are some stunning images doing the rounds at the moment, hoptefully it will give us a little show at least later in the month. Going to be difficult to view it if the lockdown is going on though from my garden. Link to comment Share on other sites More sharing options...

My northerly horizon is barely workable from home but I do have some high vantage points from work (I work a split of day/night shifts) where I can see across the town to a seaward horizon to the west and the Cumbrian fells to the north. Not anywhere I could get a telescope but I've been up there with bins many times. Link to comment Share on other sites More sharing options...

Not anywhere I could get a telescope but I've been up there with bins many times. An hours "exercise" at the 3:30am, i could easily peddle to a decnt view in 10 minutes. I think things will be little more flexible in 3 weeks though. 1 Link to comment Share on other sites More sharing options...
verreli Posted May 7, 2020 Share Posted May 7, 2020 Still a week to go before SWAN is visible from the UK but the light curve is doing strange things. From a peak of Mag4.7 it's now down to Mag5.7. That's a 2.5x decrease in brightness despite getting closer to the sun and earth. Is it going to fizzle out?... Comet chasing is a frustrating sport. 1 1 Link to comment Share on other sites More sharing options...
