GEOMAGNETIC STORM: A moderate (Kp=6) geomagnetic storm is in progress on June 28-29 as Earth passes through a region of south-pointing magnetism in the solar wind. High-latitude sky watchers should be alert for auroras. In the northern hemisphere, solstice twilight will sharply reduce visibility; southern hemisphere observers may have better luck.
