Solar flare produces threatening space storm of energetic particles

Fig. 4.28b . A powerful solar flare (Figure 4.28a), occurring at 10 hours 24 minutes Universal Time on Bastille day, 14 July 2000, unleashed high-energy protons that began striking the SOHO spacecraft near Earth about 8 minutes later, continuing for many hours, as shown in this image taken from the Extreme Ultraviolet Imaging Telescope, abbreviated EIT, on the SOlar and Heliospheric Observatory, or SOHO for short.
