Brilliant Auroras , Expected as Huge , Solar Storms Hit Earth.<br />'Newsweek' reports that auroras are expected to light <br />the night skies in some northern U.S. states over <br />the weekend as a result of geomagnetic storms.<br />'Newsweek' reports that auroras are expected to light <br />the night skies in some northern U.S. states over <br />the weekend as a result of geomagnetic storms.<br />According to the U.S. National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC), two geomagnetic storms are expected on July 22 and 23.<br />Geomagnetic storms can cause major <br />disturbances to Earth's magnetic field. .<br />They are often the result of coronal <br />mass ejections (CMEs), clouds of charged <br />particles that are shot out from the sun.<br />'Newsweek' reports that geomagnetic <br />storms vary in strength, which <br />determines how they affect the Earth.<br />The expected geomagnetic storm on July 22 <br />is likely to register the lowest on the SWPC's <br />scale, which rates storms from G1 to G5.<br />The expected geomagnetic storm on July 22 <br />is likely to register the lowest on the SWPC's <br />scale, which rates storms from G1 to G5.<br />The expected July 23 storm is predicted <br />to be a stronger G2-level storm.<br />These storms can potentially <br />impact the power grid, satellites <br />in low Earth orbit and radio signals. .<br />Additionally, the storms have the potential <br />to cause auroras, also referred to as <br />northern lights, at lower latitudes than usual.<br />According to the SWPC, auroras could <br />be seen in states including New York, <br />Wisconsin and Washington
