The Sun Today... What's this?
For any date on which SDO's AIA has been observing the Sun, you can view one set of snapshots: one image for each of the observable wavelength channels, three 3-channel composite images, and (where available) an HMI magnetogram and a blend of that magnetogram with a 171A image of the solar corona. The image summaries can be accessed showing either the current Sun or the Sun at some earlier date:
  1. http://sdowww.lmsal.com/suntoday - this will show recently processed images of the Sun's near-real time state.
  2. http://sdowww.lmsal.com/suntoday?suntoday_date=YYYY-MM-DD - this will show the last image set of the date specified.
The web pages with the above URL show:
  1. a panel with a summary of reported events from the Heliopysics Events Registry through the iSolSearch interface. This panel contains links to a users guide, to a short video demonstration, and to the main web site for the Heliophysics Events Knowledgebase with further documentation.
  2. a panel with thumbnail summaries of larger images. These images can be accessed by clicking on the links below the thumbnails, either as 1024x1024 pixel downsized images or as the full-resolution 4096x4096 images. Hover over the wavelength identifiers to view the associated thumbnail. For composite images, the wavelengths are listed in order of the red, green, and blue display channels. Each image shows the date and time it was taken; image composites show three date-time sets, color-coded by the associated display channel.
More information will be added to these pages in the near future .....

For direct access to the most recently processed images, use one of these fixed URLs: http://sdowww.lmsal.com/sdomedia/SunInTime/mostrecent/f_211_193_171.jpg - for a full-resolution, three-color composite http://sdowww.lmsal.com/sdomedia/SunInTime/mostrecent/l_211_193_171.jpg - for a 1024x1024 three-color composite http://sdowww.lmsal.com/sdomedia/SunInTime/mostrecent/t_211_193_171.jpg - for a 256x256 three-color composite

Similarly, there are direct-access URLs for each of the wavelenghts (replace 'l_' by 'f_' for the 4096x4096 versions, or by 't_' for the 256x256 versions): The thermal responses of the EUV channels are shown at http://aia.lmsal.com/public/firstlight.html#thermalresp

The AIA team is now generating and publishing daily movie summaries of the Sun as seen from the two STEREO perspectives and from SDO's near-Earth perspective. These movies can be accessed via our 'Sun Today' pages (http://sdowww.lmsal.com/suntoday/). As it takes a few days for the STEREO data to come into our archive, the movies show up 4-5 days behind current time. If the movie files are available, the links will show up automatically above the image set in the top segment of the page, immediately below the links to the "daily movies" summarizing the AIA observations (which show up with a 1 day delay behind present time).

The standard product to which the page provides links show STEREO/B SECCHI, SDO/AIA, and STEREO/A SECCHI images side by side, showing the full fields of view. All images have the N-S axis aligned vertically. No corrections for the different tilt angles out of the plane of the sky are applied. The off-disk signals have been enhanced with a radial filter in all of the images to bring out the signal increasingly with increasing height above the limb.

Other movie files are being generated in parallel to the above standard product for which the URLs show up at present: (1) 720p and 1080p versions, and (2) zoomed-in movies showing only the limbs in the STEREO data that are nearest to the Sun-Earth line. The URLs to those can be constructed as variations of the standard paths such as for these 171A movies:

There are also movies that show the AIA images at 480s cadence. These can be accessed by changing '_120s_' to '_480s_' in the URLs.

All movies show the available STEREO SECCHI images nearest in time to the cadence of the movie.
