Northern Lights may be visible Sunday night in Puget Sound area

15 Juillet 2017

Earlier on Friday a huge sunspot (AR2665 if you are scoring at home) erupted on the surface of our sun.

A coronal mass ejection is an unusually large release of plasma and magnetic field from the solar corona.

An unusually large release of plasma from the sun is expected to cause a geomagnetic storm when it begins to arrive on Sunday night, giving much of New Hampshire a chance of seeing the aurora borealis.

Storms are exciting and we have the possibility of being affected by a big one Sunday night.

Selon le musée, trois sculptures auraient été endommagées de façon permanente, engendrant des pertes de 200 000$. Au final, au moins dix présentoirs se sont effondrés.

Northern lights will be able to be seen from the North East, including the Butler region! The particles interact with molecules of atmospheric gases to cause the famed glowing red and green colors of the aurora. Remember, we are hoping for Kp levels of 6 or higher, a 7 or 8 would be awesome and nearly enure sightings of the northern lights in southern New England. The southern lights are known as aurora australis.

Peak viewing time will be from around midnight to 3 a.m., but aurora can potentially be seen through most of the overnight hours.

We are now under a "Geomagnetic Storm Watch" for July 16-17! Aurora tend to come in pulses, and don't last long.

If the auroral forecast predicts a visible aurora, get away from light pollution in urban areas and away from any bright lights. If that is the case, you'll want to quickly get somewhere where it's dark and look up.
