“Hawaii Emergency Management declared that emergency communications during Hurricane Lane will be conducted through amateur radio, which could spell trouble with the coming solar storm this week. The Sun has woken up from its slumber and has fired a solar storm our way. It should hit Earth on August 25, but an even earlier solar storm headed just south of Earth might mean we could see solar storm effects even earlier. Though this solar storm is expected to bring only mild effects, aurora is possible at high latitudes. GPS reception should remain good at low latitudes and near the hurricane affected areas, but will likely be glitchy at high latitudes, near aurora and near the dawn-dusk terminators. Learn the details of the coming storm, see how emergency communications and search and rescue will be affected, and find out what else our Sun has in store this week.”
