This image originates from Big Bear Solar Observatory in the USA
and was obtained by IPS in digital format from Solar Terrestrial
Despatch at the University of Lethbridge in Canada.
The image shows a spray of material being ejected from the sun,
being seen close to the limb, or edge of the sun. The event
occurred on August 15th, 1993.
Ejections of material from the sun may follow solar flares or other
solar phenomena. If the material reaches the earth, it can produce
magnetic and ionospheric disturbances with consequences for
HF communications, geomagnetic surveys for minerals, the
operation of long pipelines and power lines, and a host of other
effects.
