An AGU Session about a curiously ineffective active region seen in January 2014.

A presentation at OpenShow in October 2014.

The latest info about the Solar Polar Field Reversal observed at WSO. The polar field is observed with higher resolution by HMI.

Successful launch of the the Solar Dynamics Observatory, SDO took place on February 11, 2010. The instrument front door opened in late March. SDO is currently orbiting here. For the latest info on the SDO mission, check the SDO is GO blog. You can find launch preparation pictures here. Our instrument on SDO is the Helioseismic and Magnetic Imager, HMI ,

See the most recent Helioseismic and Magnetic Imager Images and movies.

This is the best portal to find HMI Magnetic Field Data.

MDI is the instrument of the Solar Oscillations Investigation on the Solar and Heliospheric Observatory. The SOHO spacecraft functioned well after launch in December 1995. Contact with SOHO was lost for several months beginning June 25, 1998. The recovery process began immediately. Contact was reestablished in July/August and by October SOHO was back from its vacation and once again operational. With the loss of its last remaining gyro, SOHO went off line again for several weeks at the end of 1998. SOHO has since been reprogrammed and has been working ever since. Because the antenna pointing no longer functions reliably, SOHO is now regularly rotated in what is now called keyhole operations. Regular operation of the MDI instrument ceased in 2010 because better data is being produced by HMI.

Synoptic maps and movies provide the most complete available picture of solar magnetic fields over the whole surface.

Our first (Jan 96) little movie of the Sun's magnetic field as seen from space was very exciting.
The Hinode spacecraft launched a decade later can do much better. Where is Hinode?  

Where is STEREO? STEREO Beacon Data

What does the Sun sound like?

NASA launched HMI , the Helioseismic and Magnetic Imager on SDO , the Solar Dynamics Observatory in February, 2010.
