- ―HoloNet News Weather Report
A solar flare or stellar flare was a sudden brightening over the surface of a star or the solar limb, which released a large amount of energy.
When solar flares hit a planet's surface, it excited mind eels, and weather forecasts recommended the watching of mind eels and their offspring during this time. These creatures did not threaten nearby farmers, as they complied with the crop boundaries set in The Relevant Farm Act of Thairwsthis 12.
