Planet Earth is under a Geomagnetic Storm Watch on Sunday and, luckily, that isn’t as scary as it sounds. In fact, some people in these situations pack up and hop on a plane – not to flee to safety, but to view the beautiful result: auroras, or the Northern Lights. Scientists recorded a partial halo CME and determined based on it’s size and intensity, that Earth will experience geomagnetic storm conditions early to mid-day Sunday. They expect G2, or moderate storm levels, and it’s predicted to cause hours of brilliant aurora. G2 storm conditions can trigger voltage alarms in power...
