Currently, the FLAMES/GIRAFFE Medusa2^(*) data are affected by a change of the slit geometry due to a major earthquake on 27-Nov-2015^(**). The currently available reference dispersion solutions are only valid before that date. The 'calSelector' service currently delivers these reference calibrations also for Medusa2 data taken after that date. Using them for pipeline processing will in most cases yield dispersion solutions of poor quality. We will replace these reference calibrations with better ones as soon as possible. The Medusa1 data are not affected by this.

Correspondingly, the in-house processing of GIRAFFE MEDUSA data, regularly published via the Phase 3 query forms, has been put on-hold. There is no instrumental issue but the pipeline needs to be updated to handle these data. We will resume processing as soon as possible.

A new archive news will be published once the problem will have been rectified.

(*) The FLAMES/GIRAFFE spectrograph is fed by a fibre system which hosts 2 MEDUSA fibre slits, one per positioner plate: Medusa1 and Medusa2. While one plate is observing, the other one is positioning the fibres for subsequent observations, therefore limiting the dead time between observations to less than 15 minutes.

(**) Mag 6.2 earthquake on November 27, 2015, epicentre at about 30km from Cerro Paranal.
