Overview
– On July 12, 2012 an X-1.4-class solar flare erupted from Active Region 1520 (AR1520), which rotated into view on July 6
– Consequently, late July 14, early July 15, a G2 geomagnetic storm impacted the Earth’s magnetic field.• Analysts at the Goddard Space Weather Lab say that satellites in
geosynchronous orbit may have been directly exposed to solar wind plasma.– The resulted in the Aurora borealis was seen in lower latitudes
• Spaceweather.com showed images of the aurora from Sparks Lake in central Oregon as well as several other locations in the northern CONUS area
– Because of the moonless night, the aurora was able to be seen in the Day Night Band (VIIRS) on board the Suomi NPP satellite• Because the aurora was within the stray light region, it was slightly washed
out. Utilizing McIDAS-V, the aurora was brought out while eliminating (for the most part) the stray light
