A M3-class solar flare from sunspot AR3032 (pictured below in red) was recorded by ESA's Solar and Heliospheric Observatory (SOHO) on June 13th ( spaceweather.com ). While the CESAR observatory was not able to capture the CME (Coronal Mass Ejection) at 04:07 UTC, we have been following the high solar activity daily.

The following is a composite image of the solar disk as captured by the CESAR helios observatory on Monday, June 14th, together with the SOHO LASCO C3 coronagraph image from the explosion ( SOHO LASCO C3 ). LASCO (Large Angle Spectrometric Coronagraph) C3 takes images of the sun's corona with a field of view (FOV) of 32 sun diameters by blocking the light from the sun's disk to create an artificial eclipse. This "occult disk" has here been replaced with an H-alpha image of the sun's disk, taken by the ground-based ESA-CESAR helios observatory on the morning of June 14th.
