The State of the White-Light Corona over the Minimum and Ascending Phases of Solar Cycle 25 -- Comparison with Past Cycles
Philippe Lamy, Hugo Gilardy
We report on the state of the corona over the minimum and ascending phases of Solar Cycle (SC) 25 on the basis of the temporal evolutions of its radiance and of the properties of c…
Observations of the Solar F-corona from Space
Philippe Lamy, Hugo Gilardy, Antoine Llebaria
The observations of the solar F-corona from space are reviewed emphasizing the 25 years of continuous monitoring achieved by the LASCO-C2 and C3 coronagraphs. Our work includes ima…
Restitution of the K and F Components of the Solar Corona from LASCO-C2 Images over 24 Years [1996--2019]
Antoine Llebaria, Philippe Lamy, Hugo Gilardy +2
We present a photometrically accurate restitution of the K and F coronae from white-light images obtained over 24 Years [1996--2019] by the Large-Angle Spectrometric COronagraph "L…
Coronal Photopolarimetry with the LASCO-C3 Coronagraph over 24 Years [1996-2019] -- Application to the K/F Separation and to the Determination of the Electron Density
Philippe Lamy, Hugo Gilardy, Antoine Llebaria +2
We present an in-depth characterization of the polarimetric channel of the Large-Angle Spectrometric COronagraph/LASCO-C3 onboard SOHO. The polarimetric analysis of the white-light…
Coronal Photopolarimetry with the LASCO-C2 Coronagraph over 24 Years [1996-2019] -- Application to the K/F Separation and to the Determination of the Electron Density
Philippe Lamy, Antoine Llebaria, Brice Boclet +3
We present an in-depth characterization of the polarimetric channel of the Large-Angle Spectrometric COronagraph LASCO-C2 onboard the Solar and Heliospheric Observatory (SoHO). The…
