Space weather forecasters said there is the possibility that more auroras could reach parts of Northern California on Wednesday, a day after northern lights dazzled skywatchers in the region.The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center’s aurora forecasting tool on Wednesday predicted a severe geomagnetic storm that is rated G4 or greater. The geomagnetic activity is also forecast to be at a KP 8 level out of a range of 0-9.According to NOAA, KP levels in the range of 8 or 9, means “the aurora will move even further towards the equator and it will become very bright and very active. These are the events that create the best aurora and the extended auroral oval will be observable by the most people. At these levels, aurora may be seen directly overhead from the northern states of the USA.”See an online NOAA aurora forecasting tool here.You can also sign up to get real-time alerts for the northern lights through Aurorasaurus.Meteorologist Heather Waldman said the chances of seeing the aurora in Northern California are lower than they were on Tuesday with cloud cover increasing. The best place for catching an aurora is away from city lights. A smartphone camera can, in some cases, catch a glimpse of an aurora that is not visible to the human eye.
