We’re heading into the next peak in the solar sunspot cycle, which will top out in the spring next year. Solar flares cause interruptions in radio activity, and can impact internet connections, marginal network boxes like routers and switches, and wireless devices.
In addition to strong radio signals and X-rays, sometimes a solar flare will send a plasma of hydrogen gas into the Earth’s magnetic field, triggering a geomagnetic storm. Geo storms impact the electrical grid and can cause power cuts and surges.
That’s why I recommend top quality surge protectors. Tripplite is my favorite brand. You can get them locally at ERI Electronics on Mottman Rd., or on-line.
