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 d'REM Team, a delocalized group of people.
8 Jun 2026 ◊ The problems with motor of the infrared camera filter wheel persists. We fixed the filter to K since this morning. Expect some error in the previous days, but from now all infrared images will be in the K band, disregarding the request in the OB.
7 Jun 2026 ◊ We are encountering some problem withe REMIR filter wheel (yes, again!). So please double check infrared images taken starting 1 June 2026.
24 May 2026 ◊ Call for proposal INAF AOT54 (October 1st 2026 - March 31st 2027 is open. The deadline is Monday 25th May 2026 at 12:00 UT. All informations and warning for REM are here. For submission package and form please follow the Proposal link.
22 Apr 2026 ◊ Successful maintenance in situ has restored full operativity of REM, including all filters in the infrared camera.
9 Apr 2026 ◊ During the next two weeks REM will undergo a set of maintenance in order to investigate the behaviour of the infrared camera filter wheel. We foresee to stop operations starting tomorrow until 20th of April.
