The southern lights, known as the aurora australis, also can be visible in far southern parts of the world such as Australia. Auroras for this storm may be visible, if weather conditions are favorable, as far south as Pennsylvania to Iowa to Oregon, NOAA reported.Į said people in cities such as Minneapolis and Milwaukee could see the aurora overhead, while cities such as Lincoln, Nebraska, Indianapolis and Annapolis, Maryland, could see it on the northern horizon.ĪURORA SCIENCE: New type of aurora, nicknamed 'the dunes,' discovered by citizen scientists in Finland Southern lights visible Down Under The storms can drive the aurora farther south from its usual position over the polar region. Weather permitting, northern lights displays could be visible directly overhead in many northern communities and visible to the North from slightly lower northern latitudes. (G1 storms are minor G5s are considered extreme.) Aurora borealis activity is currently moderate to low. This is the third level of NOAA's five-level geomagnetic storm scale. NOAA's Space Weather Prediction Center has issued a G3 (strong) geomagnetic storm watch into Thursday. Geomagnetic storms such as these can also affect infrastructure in near-Earth orbit and on the surface, possibly disrupting communications, the power grid, navigation, and radio and satellite operations, the National Oceanic and Atmospheric Administration said.ĪURORA HISTORY: Roughly 2,700 years ago, an unusually powerful solar storm swept past the Earthīut such disruptions are unlikely from this event, Lada said. "These clouds of particles are predicted to collide with Earth's magnetic field on Wednesday night into Thursday, sparking dazzling displays of the aurora," AccuWeather's Brian Lada said.Īlthough the best views of the aurora were likely Wednesday night, more are also possible Thursday night. However, the glow of the aurora probably will not be visible as far south as it was Wednesday night, AccuWeather said.Īuroras typically appear as rippling curtains of green, red or purple light. Recent explosions on the surface of the sun have sent clouds of charged particles, known as coronal mass ejections, hurtling through the solar system, according to AccuWeather. Keep an eye to the sky again Thursday night if you live across the far northern U.S.: The aurora borealis, or northern lights, may be making a rare appearance for the second night in a row. Another round of northern lights is possible on Thursday night.The storms can drive the aurora further south from its usual position over the polar region.Sunlight and clouds are the biggest obstacles to auroral observations. In order for us to see the aurora, however, the sky must be dark and clear. When the solar wind is calm, the aurora might only be occurring at very high latitudes and might be faint, but there is still aurora. NOAA's Space Weather Prediction Center has issued a G3 (strong) geomagnetic storm watch into Thursday. There is always some aurora at some place on earth.
