REM (Rapid Eye Mount) is a 60 cm diameter fast reacting telescope located in the La Silla premises of the ESO Chilean Observatory (29°15′S and 70°44′W).
The telescope hosts two instruments: REMIR, an infrared imaging camera, and ROS2, a visibile imager with 4 simultaneous passbands. The two cameras can also observe simultaneously thanks to a dichroic placed before telescope focus the same field of view of 10x10 arcmin. Thus, 5 images are obtained at the same time: g,r,i,z,IR.
The Observatory is operated for INAF by the REM Team, a delocalized group of people.


28 Jan 2020 ◊ The REMIR camera has found a solution. BUT, due to INAF balance shut down, we are stopped from any initiative until the Admin Council approves the 2020 expenditures. This is likely to happen in February. After that the procedure to reinstall the infrared camera wil take about 6 weeks. We are all VERY sorry about this.
26 Aug 2019 ◊ The techincal failure of the infrared camera Remir still prevents to allocate infrared observations.
06 Aug 2019 ◊ The OPTICON call for Proposal 2020A for REM is now open! DEADLINE: 25 August 2019 23.58 UT. See the announce. For the submission form please follow the Proposal link.
