(automated telescope aiming to catch GRB optical counterparts)
The Livermore Optical Transient Imaging System (LOTIS)
was an automated opticaltelescope system aiming to catch GRBoptical counterparts,
located at a mountain-top site (Site 300) in California near
Lawrence Livermore Laboratory.
It consisted of four 11-cm aperture
telescopes operated by a computer
that received signals of GRBs in real time.
It had a slew time under ten seconds and
a FOV of over 100 square degrees.
Its copious free time was used for
other astronomy including detecting other transients.
It was deployed in 1996, upgraded in 1998
for more sensitivity, and operated until 2001.
An improved version, Super-LOTIS (SLOTIS), a similar
set-up using a single 0.6-m telescope
was deployed in 2000 at Kitt Peak National Observatory (KPNO).
