Overview

An overview of the expected Paranal Instrumentation and Facilities to be offered for Period 105 and changes foreseen in Periods 106 and 107 is available.

UT instruments and facilities

• MOONS - the Multi-Object Optical and Near-infrared Spectrograph - is expected to be installed and commissioned at the UT1 Nasmyth A focus during the second quarter of 2021.
  
• Depending on successful commissioning during Period 103, CRIRES will be offered in Period 105 following its upgrade into a cross-dispersed echelle spectrograph.
• ERIS is expected to be installed and commissioned during the second quarter of 2020 at the UT4 Cassegrain focus.
• Depending on successful commissioning during Period 104,  a Fast Detector Readout mode will be offered for MUSE with readout time of 15s.  

VLTI instruments and facilites

• Depending on a successful commissioning, additional modes for MATISSE may be offered in Period 105.
• Provided successful commissioning, GRAVITY could be used as a fringe tracker for MATISSE (GRA4MAT) in a future period.
• ESO is evaluating the possibility of offering a focus at the VLTI for a visitor instrument during Period 105. Interested users are invited to consult the VLTI Visitor Focus webpage.

Survey telescopes and instruments

• Due the installation of 4MOST, Period 107 is expected to be the last period of operations of VIRCAM.
• Similarly, Period 107 is the last period for which the operation of VST and OmegaCAM is guaranteed under the current agreement between ESO and INAF.
