Tonight's aurora display drew a crowd on my street. Not hard to see why with the dancing green and pink auroras. The extraordinary display started shortly after sunset and well before the light had gone for the day. Red auroras were also visible for portions of the display. Poker Flats Research Range in Chatanika launched a rocket to study how the aurora affects GPS systems tonight. The rocket was easily visible from Fairbanks, 20-30 miles south of the launch site.
