Possible Aurora Activity - Keep Looking North
Ref: http://spaceweather.com/ SOLAR EXPLOSION: Magnetic fields around sunspot 484 erupted on Oct. 19th at 1650 UT, sparking an X-class solar flare. The explosion hurled a coronal mass ejection (pictured right) into space, but not directly toward Earth. There is a slim chance that the expanding cloud will deliver a glancing blow to Earth's magnetic field on Oct. 21st and trigger a geomagnetic storm. ________________________________________________ Space Weather Message Code: WARK06 Serial Number: 82 Issue Time: 2003 Oct 20 2356 UTC WARNING: Geomagnetic K-Index of 6 expected Valid From: 2003 Oct 20 2357 UTC Valid To: 2003 Oct 21 1500 UTC Warning Condition: Onset ________________________________________________ The Earth has been in a sector of the solar wind that is conducive to the production of active aurora.

Possible Aurora Activity - Keep Looking North
It was quite a strong aurora display after midnight in Norway, about 62 deg. north just after midnight last night Oct. 20/21. Very strong continuos lasting band in the sky to the north. While in zenith and and a bit down the south sky there was long strong 'blinking' bands of aurora. Hardly ever seen so long, many and lasting 'blinking' bands of aurora. What is causing this 'blinking' (on/off) of the bands? In the latter stages there was also a 'knotting' of the bands, while still blinking. Colour: white slightly green/blue, no reds observed.
