According to NOAA's Space Weather Prediction Center, an ongoing solar storm that has put on a light show across parts of North America this week may have peaked on Tuesday.

The Space Weather Prediction Center (SWPC) said on Wednesday that a second coronal mass ejection from the sun on June 22 arrived at earth earlier and with less intensity than forecasted.

Experts earlier forecasted it to be a 'strong' storm rate a G3, but eventually it turned out to be a minor storm, rated a G1.

SWPC forecasters believe the Earth got only a glancing blow from the plasma cloud as it passed.

They further stated that the earth's magnetic field is still 'agitated' so there will be a slight chance of more geomagnetic activity in the atmosphere overnight, meaning there's still a chance to see the Northern Lights for some.

"While still possible, the likelihood for most of the continental U.S. to see the aurora is not as probable as originally forecast", the SWPC said.

According to information from the University of Alaska at Fairbanks' Geophysical Institute, at high altitudes the aurora will be overhead, but in the farther south you go, the aurora will be closer to the horizon.

Experts said the best time to see an aurora is around midnight, but it will occur through the night, according to the Institute. The best chances to see one will be the three or four hours around midnight.

According to SWPC, the first thing one need to know is how strong the activity is. The KP index is used to rate geomagnetic activity from 0 to 9. According to the SWPC, the KP index for Wednesday night is four.
