[Vision2020] Aurora borealis fans

[Chris Storhok]

Hi All,

 Tonight you may be able to enjoy a decent aurora display over Moscow
(weather permitting).

 

>From the University of Alaska Fairbanks Geophysical Institute Aurora
Forecast for 12/13/06:  http://www.gedds.alaska.edu/AuroraForecast/ 

 

"Name of forecaster: Charles Deehr 

Time of prediction: 12/13/2006 9:48:00 AM*

Forecast:Auroral activity will be high(+). Weather permitting, highly
active auroral displays will be visible overhead from Barrow to as far
south as Kodiak and Minneapolis, and visible low on the horizon from
Salem, Oregon and Chicago. 

Additional Forecaster comments: The solar active region that came around
the limb last week is now facing Earth. There was a large solar flare
with attendant coronal mass ejection from this region at 0224 GMT on the
13th. This interplanetary disturbance should reach the Earth on the
morning of the 14th GMT. It could take up to 12 hours to transfer its
power to the geomagnetic field. The conclusion is watch the sky tonight
and tomorrow night in North America perhaps as far south as the middle
US and tomorrow night in Europe as far south as northern Europe. The
aurora should be visible also from Tasmania and South New Zealand.
You can watch our simulation of the shock travel from the sun to the
planets if you go to http://www.gedds.alaska.edu/AuroraForecast/
and click on the black map on the left side of the page to watch the
Java movie of the interplanetary shock.
Click on the short-term (1 hr) forecast map on the right hand side of
the page to see what will happen in the next hour. That way you won't
have to stand around outside like those in the maritimes right now in a
36 deg. drizzle and watch the cloudy sky. 
If it is clear where you are, watch for the Geminid meteors too. 

*	Alaska Daylight Time (AKDT) is 8 hours behind Greenwich Mean
Time (GMT) or Universal Time (UT). Alaska Standard Time (AKST) is 9
hours behind GMT or UT. "

 

Hopefully you will be able to enjoy the show.

Chris
