2006 QV 89 - Can we rest assured?

Recommended Posts

If it was supposed to be so damaging, I'm surprised no one has bothered to keep an eye on it after its discovery. But I guess we should at least be encouraged by the fact that they can't find it in the dangerzone.

I thought that too!

Mind you, I guess it does to some extent depend on the accuracy of the reporting. I'm not sure 'the register' counts as top-of-the-range reporting.

While The Register do try to put some humor in the titles and content of their stories, they do seem to be credible. In the case of 2006 QV89 I did a quick search and the Wikipedia article on it corroborates what is reported by The Register. More seriously, it looks like there is room for improvement in our ability to reliably track Near Earth Objects that might be a threat. For this object the VLT had to be used to rule out the chance of impact and I am sure getting observing time on telescopes of this class is very competitive. The LSST which is supposed to be starting operation in 2020 has tracking of Near Earth Objects as on of its scientific goals so should improve our abilities in this regard. But maybe we should be more worried by being struck by an Unmanned Autonomous Vehicle.https://www.theregister.co.uk/2019/07/19/selfdriving_bus_injuries

OK, I hadn't checked the magnitude. Sitting between 22 & 25.3, I guess it does take quite a big scope to record it, so your point is well-taken.

I remember reading a few years back about a similar-sized asteroid that was discovered four days after it's closest approach to earth. If I was going to worry about this sort of thing at all, I think this would be the concern of choice!

      Back in March I was granted an observatory code ( Q69 ) by the Minor Planet Center ( MPC ) and since then I have been spending all my available telescope time ( which due the weather has admittedly not been very much  ) to capturing images of asteroids, that the MPC is interested in recieving data for, and sending in the positions that I have determined.
      Mostly I have been focused on asteroids that have not been observed/reported on during their current return to visibility.
      2014 LA21 was my first after getting my code ...



      Here I was the first to report astrometry for 2014 LA21 since 2016 - not like discovering a new comet I imagine but still, a small achievement and  a nice feeling
      You may have noticed that I don't as yet supply any brightness data; this is because I have not figured out how I can do this reliably ( most of the asteroids I am chasing are very dim and so my 4 minute exposures tend to spread them a little making them hard to compare to nearby stars ).
      I have been getting reasonably good position data though, with a "variation to average path" across the samples of sub 1 arcsec ( typically less than 0.5 and sometimes down as low 0.15 )
      ....
      Anyway, I was just thought I would let people know what I have been up to and why you have not seem me latley over on deep sky imaging forum and also, I was wondering if there is anyone else here on Stargazerslounge doing the same thing ...

      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:
