Halloween 2003 Solar Storms: SOHO/EIT Ultraviolet, 195 Angstroms

Here is a view of the full solar disk during a two-week period in October and November of 2003 which exhibited some of the largest solar activity events since the advent of space-based solar observing.

The Extreme ultraviolet Imaging Telescope (EIT) collects solar images in an extremely short wavelength of ultraviolet light, not visible from the surface of the Earth. The narrow wavelength band at 195 angstroms corresponds (19.5 nanometers) corresponds to a spectral line of multiply-ionized iron atoms.

This movie is part of a series of movies with matching cadence designed to play synchronously with each other. The other movies in this series are

• Halloween 2003 Solar Storms: SOHO/EIT Ultraviolet, 304 A
• Halloween 2003 Solar Storms: SOHO/MDI Continuum
• Halloween 2003 Solar Storms: SOHO/MDI Magnetograms
• Halloween 2003 Solar Storms: SOHO/EIT and SOHO/LASCO
