H-Alpha Chromosphere Observed from Space Weather Precidction Center (SWPC)

Published by DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 06:13 AM | Dataset Last Updated: August 15, 1967 at 12:00 AM
In 1967 Boulder became one of the SPAN observatories when it received its Razdow Telescope. The telescope would be used to observe solar flares and related solar phenomena. Using a Hydrogen - alpha filter that blocks most of the light, an observer could look through an eyepiece at the Sun, and a 35 - mm camera could take constant film footage of the Sun. This dataset shows many of the 35mm images that were taken by forecasters at the Space Environment Lab (SEL) now known as SWPC.
