Halloween Solar Storms from SOHO/EIT, 304 Angstroms
This view from SOHO/EIT in the 304 Angstrom band, shows a group of active regions rotating back into view. This movie is synchronized to play with animation IDs 2959 (http://svs.gsfc.nasa.gov/vis/a000000/a002900/a002959) and 2961 (http://svs.gsfc.nasa.gov/vis/a000000/a002900/a002961). One obvious difference is that solar flares are not as visible at this wavelength than at the 195 Angstrom band. The 304 Angstrom filter was not used as frequently as the 195 Angstrom filter, so this movie has more jumps in its time coverage. For more information on how X-ray solar flares are classified (B, C, M, X), visit (http://www.spaceweather.com/glossary/flareclasses.html).

This movie shows over two weeks of high solar activity visible from SOHO-EIT at a wavelength of 304 Angstroms.    This movie shows over two weeks of high solar activity visible from SOHO-EIT at a wavelength of 304 Angstroms.
