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.


30 Apr 2020 ◊ Call for proposal INAF AOT42 (2020B) is open. The deadline is 01 June 2020 at 12:00 UT. The infrared REMIR camera, presently unavailable, is foreseen to be repaired by mid 2020. Programs which were stopped due to La Silla shutdown will be put in a queue in the next semester, if possible. We suggest to submit a new proposal in order to get higher priority.
All informations and warning for REM are here. For submission package and form please follow the Proposal link.
20 Mar 2020 ◊ Due to the La Silla Observatory shutdown in view of the COVID-19 consequences, REM will accordingly stop observations from Monday, 23rd of March 2020 until further notice. Take care!
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.
