THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MAJOR STORM LEVELS. THE DAY BEGAN WITH QUIET TO UNSETTLED CONDITIONS. A SINGLE PERIOD OF MAJOR STORMING WAS OBSERVED AT BOULDER DURING 05/0600-0900Z, WITH MORE EXTENSIVE MINOR STORMING OBSERVED AT HIGHER LATITUDES DURING 05/0600-1200Z. THE REMAINDER OF THE DAY SAW UNSETTLED TO ACTIVE CONDITIONS.
