AURORA WATCH: Earth is slipping into a solar wind stream

Ref:http://spaceweather.com/

AURORA WATCH: Earth is slipping into a solar wind stream flowing from
a coronal hole on the sun; so far the encounter has done little to
spark auroras. There's still hope for some geomagnetic activity this
weekend, however, because a coronal mass ejection (CME, movie) is
heading toward Earth, due to arrive on May 28th or 29th. The CME is not
a big one, but it might spark high latitude auroras over, say, Canada
and Scandinavia.

Space Weather Message Code: WARK05
Serial Number: 490
Issue Time: 2005 May 28 1730 UTC

WARNING: Geomagnetic K-index of 5 expected
Valid From: 2005 May 28 1730 UTC
Valid To: 2005 May 28 2359 UTC
Warning Condition: Onset
NOAA Scale: G1 - Minor

That's interesting, but I wonder how we could destinguish the aurora in the
bright skies we have here (60N) all night at this time of year.....?

Btw. here's the Sun as seen from Norway just 30 minutes ago (~11:00 UT)
