A GIF animation of 322 x3 second frames showing NEO 3200 Pheathon during its close approach in December last year. It's taken me a while to get around to putting this together...

Animation2.gif.e9f2d8f956f1900d063e3ceb5fa2de9d.gif

Frames were taken during the early evening of December 14th 2017 between 18.11.06 UT and 19.44.57 UT as the object crossed the Perseus/ Andromeda border.  The field is just under a degree wide.  What I think is a sporadic meteor crosses the field about a second in.  I could not find a satellite ID for that time and region, nor do I think it is a Geminind as it seem to come from the wrong radiant.

Any comments or observations welcome.

Excellent work. Well done! :)

'Phaethon' was +2° above the horizon at the time stated above, So I assume you imaged it in December.
Observations? Aside from the animation being severely clipped, it is great. Good work.

Great! It reminds me of the Enterprise as it boldly goes where no one has gone before

Thanks.  I got the month wrong, yes. I will correct the post.  As for “clipping”, the aim was to depict the asteroid movement against a background not too dissimilar from an eyepiece view.  3 second subs to miminise trailing and a requirement to try and keep the GIF file size down restricted the amount of background detail that could (or needed) to be shown.  Moving the dark point over to the left on the sub histograms resulted in a shimmering of the background in the animation that I find annoying.  It’s a compromise.  Thanks for the comment though.

Thats fab!  It shows nicely with the dark background.  Well worth the wait!

      On March 31, 2018 issue of the Minor Planet Circular, the asteroid previously known as 2001 HQ16 was named.

      (72834) Guywells is a Main belt asteroid with a diameter of 3-6 km. It last came to opposition in February 2018 when it reached 18th magnitude. Now it is moving through the constellation Cancer, observable  at mag +19.5.

      (72834) Guywells was discovered by L Ball, in 2001.

      Hi, after almost 2 months of clouds there was finally a clear night in sight. I made most of it, imaging until clouds rolled in about 4 in the morning.
      I shot these using two telescopes at Taurus Hill Observatory. Its fun to operate two at the same time, luckily its possible from indoors.
      Ill also attach here light curve of variable star V0416 UMa that I made during the same night with C14 and SBIG ST-8 on Paramount ME mark II. Other images are taken with 16" f/8 Meade SCT and SBIG STT8300M on Paramount ME mark I. Im expecially happy with Dembowska, I tried to get complete light curve twice in 2017 but clouds or fog always ruined my photometry.

      Milkyway was also beautiful as always, I spent some time outdoors just looking at it while telescopes clicked more subs. Worth every second in the cold, windy night!

      I've been following somebody on Facebook who regularly images asteroids, and indeed has identified a few of his own.
      But this got me to wondering, do these orbiting bodies, of which there must be many thousands, all reach the same kind of velocity?
      I guess there are various factors involved. This new asteroid from another galaxy is also intriguing.
      For what it is worth, here are a couple that I have observed in the past:

      The Kingsmen are at it again! And this time, they've been ordered to chase down the rapidly moving interstellar asteroid 'Oumuamua to make analyses and to make sure it doesn't collide with any of the planets in our solar system. It includes images from the ESO, NASA/JPL-Caltech, Pan-STARRS1, and the University of Wisconsin. I wrote the storyline, did the character and spaceship illustrations, performed the voice characterizations, created the AfterFX space animations, and composed the music (as The False Dawn).I hope you enjoy this little adventure!
       
      The Kingsmen, excelsior!

      Did anyone try observing the predicted occultation of a faint star by the asteroid Massalia on 17th Nov 2017 at around 01.30 am? I saw a prediction and tried to observe it, but was defeated by my telescope misting up after a long spell in the open, despite a dew shield.
