That’s what the University of Alaska’s Geophysical Institute is predicting, saying the giant eruption technically not a solar flare, despite Internet buzz will mean a larger-than- usual viewing range for the northern lights Wednesday night. The institute predicts Washington D.C., Nebraska and Portland might even get a peek.
An event on the Sun occurred on the 7th of June. Prompt arrival of high speed particles has already affected the atmosphere. Our model indicates that the shock wave will reach Earth on the 8th of June around 5pm GMT. This will be followed by a disturbance in the solar wind that should produce fairly extensive auroral displays within 24 hr after that time…
It is difficult to predict what the K index will be during night of the 8th in North America, but it is reasonable to expect K=6 which would put the aurora over Milwaukee, and visible on the northern horizon on a line from Portland Ore, southern Nebraska, southern Indiana, to Washington, DC.
That means if the sky is clear, your eyes should be on the northern horizon around midnight local time, according to experts. Of course, at the time this post was published Wednesday evening, Seattle was socked in with a thick layer of cloud coverage.
