However, the heightened interest and anticipation of the event has satellite professionals on their toes, says Schram. Also, during that time of day for the satellites, the sun angle relative to the solar panels is already pretty favorable. We're kind of fortunate, and we're looking at whether or not we cap them any further, or even if that's necessary given the low probabilities. Here's an abbreviated glossary of terms for those who have a budding interest in all things solar. A region on the sun which is active.
Active regions contain strong magnetic fields.
Flares occur within active regions. The outer atmosphere of the sun with low density and high temperature. Visible as an extended bright region about the sun during a solar eclipse. Coronal holes are the sources of high-speed solar wind streams. An ejection of material from the sun into interplanetary space.
