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.
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...
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.
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:

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.
