- Abstract:
-
The January 20 flare began just before 2 a.m. ET. A storm of energetic protons impacted Earth just 15 minutes later. These views of the flare are from the Solar and Heliospheric Observatory (SOHO). The proton storm near Earth causes `snow in the images, obscuring the Sun as radiation swamps the cameras. The structure at the 1:30 position in the SOHO-LASCO-C3 data is the occulting disk pylon.

The SORCE mission monitors solar variability to determine its impact on the Earths climate. The X-ray photometer aboard SORCE observes the record-breaking solar flares in the Fall of 2003. The line graph shows the photometers measured solar radiation flux in the 1-7 nanometer wavelength band (x-ray) measured in milliwatts per square meter. The ultraviolet (195 Angstrom) imagery from SOHO-EIT (green) illustrates where the flares (the bright white spots) are located on the solar disk. This version has the contents slightly smaller for use in video.

Push-in to a region of the Sun to witness a solar tsunami after a flare event. The tsunami moves hot gas (bright) out of the region, revealing cooler regions (darker) below. This view rotates on the push-in to keep the region of the flare event visible (to the left in the final frame).

- Abstract:
-
On November 4, 2003, the Sun produced its fastest coronal mass ejection (CME) for cycle 23 out of the active region 0486 located near the southwest limb of the Sun. The CME was expelled with a speed of approximately 2700 km-s. At the time of the launch of this CME, there was another ejection in progress from the same region. The previous ejection started about 7 hours earlier with a speed of about 1000 km-s. The fastest CME overtook the previous one within 2 hours and produced a spectacular radio radiation detected by the Wind, Ulysses and Cassini spacecraft. The movie shows the radio emission and the two interacting CMEs as observed by the SOHO spacecraft.
