An RAS Specialist Discussion Meeting organised by Iain Steele*, Mike Bode, Chris Davis, Chris Copperwheat (All LJMU)*Contact: i.a.steele AT ljmu.ac.uk The robotic 2m Liverpool Telescope, based on the Canary Island of La Palma, is owned and operated by Liverpool John Moores University, with operational support from STFC. It has a strong track record of service to the time domain community in the UK and beyond. The next decade will see time domain science becoming an increasingly prominent part of the astronomical agenda, and the LT will continue to be at the forefront, with large programmes exploiting new transient sources discovered with facilities such as iPTF, Gaia and LOFAR. Looking further into the future, the next generation of surveys such as LSST will revolutionise the study of the time variable sky, and facilities such as CTA will probe transient phenomena at previously unexplored wavelengths. New exoplanet finders, starting with NGTS and followed by the next generation of space missions, will improve on Kepler by discovering more planets with bright host stars in order to maximise the potential of ground based follow-up. In addition, the anticipated discoveries of electromagnetic counterparts to astrophysical gravitational wave and neutrino sources will open new windows on the transient universe. There will be a pressing need for follow-up facilities for scientific exploitation, in particular spectroscopic follow-up. With that in mind, plans are underway for Liverpool Telescope 2: a new 4-metre robotic telescope to be built on La Palma, with a world-leading response time for follow-up of the most rapidly variable objects. http://telescope.livjm.ac.uk/RASMeeting/
