The Liverpool Telescope is a 2.0 metre unmanned fully robotic telescope at the Observatorio del Roque de Los Muchachos on the Canary island of La Palma. It is owned and operated by Liverpool John Moores University, with financial support from STFC.

CCI Call For Proposals 2016

The International Scientific Committee (CCI) of the Roque de los Muchachos (ORM, La Palma) and Teide (OT, Tenerife) observatories invites applications for International Time Programmes (ITP) on telescopes installed at these observatories. The ITP offers up to 5% of the observing time, which amounts to 50 hours per year for the LT. The deadline is 29th February 2016. [full story]

Fringing before and after new CCD replacement
High-resolution spectrograph FRODOSpec receives upgrade

The Liverpool Telescope high resolution fibre-fed spectrograph FRODOSpec received a CCD detector upgrade in October which brought two major benefits - increased sensitivity and a large reduction in fringing. Overall, this CCD upgrade coupled with the telescope secondary mirror realuminisation means more objects are now within range of FRODOSpec than ever before.

LT Public Data Archive Exceeds Two Million Files

The latest Liverpool Telescope public data release consisted of 118,474 new files, including both spectra and images spanning from the ultraviolet u’-band to the H-band infrared, bringing the total number of observations freely available from the archive to over two million.

There are now over 13,000 hours’ worth of observing data available, 9960 hours imaging and 1636 hours spectroscopy. Most targets have been observed a few times, going back to the start of LT operations in 2004, but some fields, such as the photometric standards, have time series consisting of thousands of observations.

Secondary mirror being removed
LT maintenance: mirrors realuminised and throughput doubled

The middle of June saw the Liverpool Telescope go offline for two and a half weeks, to successfully undertake important scheduled maintenance. The main item in the to-do list was to realuminise the telescope's primary and secondary mirrors. This difficult task was performed outstandingly, and the results were clear to see, in that the throughput of the telescope was doubled - i.e. twice as much light now enters the telescope's detectors as before.

When stars collide: LJMU team identifies rare luminous red nova in Andromeda

In January 2015 the discovery of a possible classical nova in the Andromeda Galaxy (M31) was announced by the Global MASTER Robotic Network, a Russian-led network of telescopes dedicated to time domain astronomy. Classical novae are not particularly rare events, with around 30 observed each year in M31 alone. However, as the LJMU team of Steven Williams, Matt Darnley, Mike Bode and Iain Steele were soon to realise, the object in M31 was a much more unusual object. By following the outburst with the Liverpool Telescope's new spectrometer SPRAT and its work-horse imager IO:O, Williams and co. demonstrated that the outburst - dubbed M31LRN 2015 - was not a classical nova, but was instead a luminous red nova (LRN), a much less common class of stellar transient.
