We rely on advanced technology for almost everything we do today. Satellite communications, GPS applications, and the electric power grid provide the backbone to our Nation’s economic vitality and national security. This technology however, is vulnerable to a threat from space — our Sun. Eruptions from the Sun can have a profound impact on society. In Boulder, Colorado NOAA space weather forecasters maintain a constant vigil on the Sun, alerting a diverse customer base when storms are imminent. Operators from many sectors will take mitigating actions to protect the critical infrastructure that we have come to depend on.

This is why ham radio operators need to be prepared for such a massive solar event. If the rest of the grid (power and internet) were to go down, it could take a long time for it to be repaired. Ham radio communications might become critical in every community. Are we prepared and proficient to aid our communities?

This is a good website to find all sorts, configuration and strengths of magnets for all kinds of projects. (I made a inexpensive stir-plate to propagate larger volumes of yeast to pitch into batches of homemade beer using Neodymium magnets glued to an old computer fan.)
