Mostly quiet conditions are expected to continue until later >this UT day when effects from an anticipated solar coronal mass ejection >should impact the Earth's magnetosphere, resulting in a minor intensification >of auroral activity. The next 3 to 5 days should be unsettled as we >expect one of possibly several minor coronal mass ejections to impact the >Earth's magnetosphere and produce periods of unsettled to briefly active >auroral activity. Unfortunately, the near-full phase of the moon will >significantly hamper attempts to view activity from the middle latitudes. >The best opportunities for observing possible activity will be sometime after >the sun sets and before the moon rises in the early evening. The most >significant period of activity may accompany the arrival of a solar filament >associated coronal mass ejection that was observed earlier today. This event, >which should impact the Earth sometime late on 27 or on 28 June, has the >potential of producing slightly stronger levels of auroral activity, but >still probably nothing too significant. > > NOTE: Northern high latitude stations are now experiencing adverse > seasonal twilight conditions. Regular reports from the higher northern > latitude stations will therefore cease until later this fall. > > ** End of Aurora Report ** > > > >
