Graph showing the progression of the 11 year solar cycle. In October 2003, sun spot activity
was on the decrease following a peak in 2000.
Michelson Doppler Image of the sun on October 28, 2003. This image shows three large sunspot groups.
The group located in the low center of the image is 486, where a very intense solar flare originated.
SOHO (Solar and Heliospheric Observatory) image showing the coronal mass ejection associated with the intense
solar blast on October 28 in the form of a full halo surrounding the sun.
The full halo is indicative of an earth directed eruption.
The spike on the left side of this graph traces the abrupt arrival of x-rays arriving in the near-earth environment shortly
after the intense solar flare on October 28. The spike on the right depicts a second powerful solar eruption which occurred on the afternoon of the 29th. The effects of the most recent event are yet to be determined as of this writing.
Images captured along County Road 60 and Highway 158 just northwest of Midland between 0240 and 0305 CST
(0840 and 0905 UTC) showing the intense aurora substorm.
Image taken at approximately 0400 CST (1000 UTC) from Highway 158 of faint and diffuse auroral glow.
