Details:
This auroral event was the largest recorded in scientific history at the time. Instruments used to monitor space storms and geomagnetic disturbances were saturated beyond their high-end capacities to the highest event levels ever recorded. Data derived from this event was only a “best guess” by the scientific community because these levels had never been experienced. K-values were 8's & 9's and the 24-hour AK-value was adjusted up to a whopping 289! The solar flare responsible for this aurora was decided as an “X15 Bright” and knocked out power to millions of folks in Ottawa, Canada. Radio communications across the world were also disrupted for several days. In the “aurora-chasing” world, the Great Pink Aurora danced across the dawn with the very rarest of the color spectrum. This grand display appeared across Alaska's southern skies beyond 6,398 foot Pioneer Peak in the Chugach Mountains of the Matanuska-Susitna Valley. Perhaps Cycle 25 may give the world such a show again?
