Flyby of asteroid 2004 BL86


Asteroid 357439, 2004 BL86, discovered in 2004 by LINEAR (Lincoln Near-Earth Asteroid Research), passed within 1.2 million km of the Earth (about 3.1 times the distance of the Moon) on 2015 Jan 26, with closest approach at 16:19 UTC. Having a diameter of about 500m, 2004 BL86 is largest known asteroid to come this close to Earth until August 7, 2027 (when asteroid 1999 AN10 will come within about 1 Moon distance).

The flyby was observed at UCLO by Steve Fossey and Thomas Schlichter, using a C14 telescope and SBIG STL-6303E CCD camera; Ian Howarth compiled the data frames into the short video shown above. Field of view is approximately 18x24 arcminutes; North is up, East to the left.

First observations by fibre-fed spectroscopy

The first spectrum of an astronomical source obtained through a fibre feed was taken on 2013 July 11. The observation, of Venus, was obtained using a fibre link from the C14E to the Shelyak Lhires III with an ST8XME camera. The fibre coupling was developed by PhD student Nic Clarke, under the supervision of Bruce Swinyard, with assistance during commissioning from Steve Fossey, Mick Pearson, Andre Munoz, and Nicola Baccichet.

UCLO Affiliates to the Worshipful Company of Clockmakers

The close historical association between astronomy and timekeeping has been recognized by an invitation of affiliation from the Worshipful Company of Clockmakers

The affiliation was formally marked on 2013 January 24 at UCLO, when the Master of the Clockmakers, Mark Elliott, presented the Clockmakers' Shield of Arms to the President and Provost of UCL, Professor Malcolm Grant. We look forward to a long and fruitful relationship.

First Light for Remotely-Conducted Observations at UCLO

The Observatory is developing the capability of operating suitable telescopes from off-site, a process initially made possible by a CIF grant allowing purchase of equipment enabling a dome to track the motion of the telescope it houses. Over the summer months a concerted and continuing effort has been made by Observatory staff to tackle remaining mechanical and software challenges, with undergraduate involvement made possible through bursaries provided by the Nuffield Trust and the Royal Astronomical Society.

A milestone in this process was passed on 2010 July 21, when student Jakub Bochinski controlled a C14 telescope and its CCD camera from his home in central London, using a web-based interface – the first remote observation to be conducted at UCLO. As well as calibration frames, a set of 'first light' images of the planetary nebula M27, shown below, was obtained.

A number of operational matters have yet to be resolved, and routine remote observing still lies well ahead. Nonetheless, the success of this experiment, attributable to the combined efforts of all the technical and academic staff at the Observatory, demonstrates great promise for future progress in this direction.

When Art Meets Astronomy

What happens when art and astronomy meet? Artist Katie Paterson has joined UCL's Astrophysics Group as their first Artist in Residence, thanks to a grant from the Leverhulme Trust. During the residency, Katie will investigate ideas of Ancient Darkness and Early Light in the Universe, Dark Energy, Dark Matter, and very distant objects, and create a new body of artwork alongside her findings. Katie graduated from the UCL Slade School of Fine Art in 2007.

The following video, which includes much footage obtained at UCLO, outlines some of the concepts and ideas

BBC Stargazing LIVE at UCLO

As part of the BBC's 'Stargazing LIVE' event, the Observatory held an open evening on 2011 Jan 7. Visitors were given a short introductory talk and a tour of the domes. Dismal weather conditions meant it wasn't possible to observe Jupiter, but nevertheless almost 200 guests braved cold weather (and occasional rain) to look round the site.

Although we were set up for a live webcast of Jupiter imaging through the BBC, weather foiled our plans.
