SDO is the Solar Dynamics Observatory and HMI is the
Helioseismic and Magnetic Imager aboard the spacecraft
which is in geosync orbit.  A large (~ 1.8 MB) HMI image of
the sun (4096x4096) has been colorized and annotated here
with all sunspots identified:

Please use the above link to download the full image and
zoom in to enlarge sun spots.  The Thumbnail below is a
~ 75 KB version of the image (double click it for the UT).

-----------------------------------------------------------
Note:  The unprocessed data (from which the above JPEG
images were derived) comprise ~10 MB in GIF format, are
updated every 15 minutes, and can be accessed here:

Also below is an H alpha image of the full sun taken with
one of the GONG (Global Oscillation Network Group)
telescopes on the same date and at a UT near that of the
above HMI image.  Double click the H alpha image for
the GONG telescope used and the UT.

 

Cheers,

The animation below is El Teide data taken today from 0708 to 1135 UT

and comprises 27 frames that are compressed into 5.4 seconds.  Note

that there is plenty of plage activity.  Normally Cerro Tololo data is

preferred but that site has been down for the last 4 days.
