Space Weather: A Brief Introduction
This 5-minute video clip with narration gives a coherent overview of the magnetic activity from the sun that we call 'space weather' -- how the Sun creates it and how this phenomenon creates aurora. The original animations provide an easy-to-understand explanation of the science, including the complex concept of magnetic reconnection that is at the root of most space weather. It was developed using content from many Norwegian research institutions by http://www.forskning.no, Norway's leading science portal on the web.

April 22, 2004
Recovery from ESR has been postponed until tomorrow.
SOHO entered ESR (safe) mode at 07:27 UT. The ESR was tiggered by another spurious FSPAAD (Fine Sun Pointing Attitude Anomaly Detector) anomaly. Recovery is in progress.

The Sun-Earth Connection:
Between 18-23 March 2003, scientists across Europe and the world will be meeting the public to explain the newest theories about the way in which the Sun connects to and affects life on Earth. The Sun-Earth Days are an international celebration of our Sun and its connection to our lives, with exhibits and lectures to promote public awareness of the dynamics of our Sun and its influence on the Earth.

A front-row seat for the Sun-dancing comet
Although the spectacular comet NEAT will not be visible in the LASCO images until about 16:00 UT on February 16, it has in fact been tracked by SOHO's SWAN instrument since December 31 last year. The LASCO pictures of this comet are expected to be quite out of the ordinary, with a sizeable tail and a very bright (saturated) comet nucleus.

A Well-Studied Comet
With the LASCO coronagraph, SOHO observes many sungrazing comets as they plunge into the Sun. Some of the brighter ones are also observed in ultraviolet light, when possible, with the UVCS instrument. One of the latest comets was caught at three different heights.

SOHO is preparing for Momentum Management/Station Keeping maneuver:
~15:00 UT currently in RMW (Roll Maneuver Wheels) mode.
February 6, 2002
Instruments are being turned on one by one, checked out and safed manually, in preparation for a station keeping and momentum management manoeuvre which is planned for Friday, February 8. Tomorrow, the spacecraft will be put into RMW (Roll Manoeuvre Wheels) mode in preparation for the manoeuvre, and some further instruments may be turned on if time allows.
February 5, 2002, 12 UT
SOHO is now in CRP mode.
February 5, 2002
Around 02:30 UT on February 5, 2002, SOHO went into Emergency Sun Reacquisition (ESR) mode shortly after an interruption of the power supply to one of the reaction wheels. Power to all the instruments was also interrupted. Recovery from ESR mode into Coarse Roll Pointing (CRP) mode is proceeding, and the cause of the events is under investigation.

A Fiery CME: Another spectacular Coronal Mass Ejection (CME) took off from the Sun in the early hours of January 4, starting off as a filament eruption seen by the Extreme ultraviolet Imaging Telescope (EIT) in the 195 Å images. The complexity and structure of the CME as it passed through the Large Angle and Spectrometric Coronagraph (LASCO) C2 and C3 fields of view amazed even experienced solar physicists at the SOHO operations center.
Exclusive Views of Comet 96P/Machholz: You could see it easily with your unaided eye (but don't try!) if only Comet Machholz 1 were not so very close to the Sun. The best, and perhaps the only view of it near perihelion comes from SOHO. As an added bonus, Venus appears in the images, and a CME erupts as the comet passes by.
