June 8: watch the Venus transit live

Newsflash: SOHO can see again!

The SOHO team announced on April 27, 2004 at 21:00 UT that SOHO is back in normal mode. The satellite can continue its scientific mission. This is indeed a great relief for us, forecasters. Underneath the first EIT-movies made since the satellite is again in normal mode.

SOHO has become blind!

The EIT-telescope as well as LASCO have become temporarily blind. An onboard computer remarked a virtual malfunction and ordered the satellite to go into the 'safe' mode in which only vital functions are kept alive.

Newsflash broadcast on the SOHO-webpage on April 21, 2004
"... SOHO entered ESR (safe) mode at 05:37 UT. The ESR was triggered by the FSPAAD (Fine Sun Pointing Attitude Anomaly Detector)."

Sun-Earth Connection Day

The SIDC will actively participate in the Sun-Earth Connection Day, a worldwide ESA/NASA event to promote the public awareness of the dynamics of our Sun, the resulting Space Weather and its influences on Earth. Check this website for upcoming activities.
