Space Weather News for July 19, 2002<br />http://www.spaceweather.com<br /><br />Another coronal mass ejection is heading for Earth. It was hurled into<br />space Thursday, July 18th, by an explosion near the huge sunspot 30. The<br />expanding cloud could trigger geomagnetic activity when it sweeps past our<br />planet. Sky watchers--especially those at high latitudes--should be alert<br />for possible auroras after nightfall on Friday and Saturday.<br /><br />Meanwhile, sunspot 30 remains impressive. It stretches 15 Earth diameters<br />from end to end. A second spot (active region 36) has grown nearly as<br />large in recent days. You can see both--but NEVER STARE DIRECTLY AT THE<br />SUN.
