SUMMARY:Guiseppe Nistico (Università della Calabria): First observations 
 from the Solar Orbiter/Metis coronagraph
TZID:Europe/London
UID:20230125-8a17841b85bb0e180185bf4b52b5133b@warwick.ac.uk

DESCRIPTION:Abstract: The recent launch of the Solar Orbiter (SolO) missi
 on in 2020 has offered new opportunities for the study of the physical p
 rocesses occurring in the solar atmosphere from a vantage point of obser
 vation of about 0.3 AU. The Metis coronagraph aboard the SolO spacecraft
  is able to take images of the inner corona in visible light and in ultr
 a-violet\, in the Ly-alpha line of the neutral hydrogen at 121.6 nm\, in
  a narrow region between 1.7 and 3.1 solar radii from the disk center. S
 imultaneous observations of the corona in visible and UV light open the 
 possibility to infer velocities of plasma in the corona by adopting the 
 Doppler dimming technique. In this talk we review the first observations
  collected by Metis\, with a special focus on the observations of sungra
 zing comets\, which offer a further way to diagnostic the local properti
 es of the coronal plasma.
