Coronal mass ejections (CMEs) are observed in the plane of the sky in coronographic images. As the solar surface is masked by an occulting disk it is not clear whether halo CMEs are directed towards or away from the Earth. Observations of the solar c

Multi-wavelength imaging of the solar corona is a powerful observational method to study CME-related dynamics of structures in spectral bands related to the solar corona and transition region. We analyze large-scale eruptive events caused by halo-typ

We report the first observation of a filament eruption in the metric and decimetric range, where the behavior of the filament can be followed during the event via thermal radio emission diagnostics. The event, occurring on February 28th 2001, involve

The large solar flare of 14 July 2000 10 UT occurred in an active region near the central meridian. It was accompanied by the eruption of a lament and a rapid halo-type coronal mass ejection (CME). Large particle fluxes were detected up to relativist

A campaign of observations with EIT on board SOHO called “CME watch”, is designed to observe the whole sun surface in 195 A i.e. in a Fe XII emission line, every 17 minutes. In order to analyze the events, we also used He II and coronagraph obser

We present preliminary results on solar filaments observed from the ground and from SOHO in September 1996. Motions in the network and close to the filament “barbs” are shown at different levels of the chromosphere and the transition region.

Simultaneous XUV and microwave (μ – ѡ) observations of a solar filament, performed by several instruments onboard SOHO and by the Very Large Array (VLA), are analyzed. The filament appears as a dark structure, very similar in shape to the optical

EUVITA is a set of 8 extreme UV and soft X-ray normal incidence imaging telescopes, each of them sensitive in a narrow band (λ/Δλ=15 to 80), centered at wavelengths between 50 and 175 A. Each telescope has an effective area of a few cm2, a field o

International audience; We report on a Coronal Mass Ejection (CME) observed on June 27, 1999 by the UltraViolet Coronagraph Spectrometer (UVCS) telescope operating on board the SOHO spacecraft. The CME was also observed by the Large Angle Spectroscop

Using multi-wavelength observations, in particular in imagery, recorded by SOHO/LASCO-MDI, Yohkoh/SXT, the Meudon spectroheliograph and the Nancay radioheliograph, and performing a linear force-free field extrapolation, we analyzed the triggering and
