On account of the activities related to the installation of MUSE, NACO will be dismounted from the Nasmyth platform of UT4 and unavailable from 2 September 2013. At the time of releasing the Call for Proposals the exact timeline of MUSE arrival was not finalised and it was anticipated that NACO would be removed during Period 92. The MUSE Consortium and ESO Instrumentation have now confirmed that the installation and commissioning activities will start towards the end of January 2014. To allow the required modifications of the Nasmyth platform of UT4, NACO will be disconnected at the end of Period 91 and it will therefore be unavailable for the whole duration of Period 92. The instrument will be stored for future re-use.
