Magnetic flux

Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet to unsettled levels during days 1 - 2 (16 - 17 February) with a chance for active levels. Activity is expected to decrease to quiet levels on day 3 (18 February).

I posted this question in another thread:

Can anyone say if there is a correlation between disruptions in the magnetosphere and quake activity?

AC 765273,

Yeah that's possible [link to www.swpc.noaa.gov] will show you the POES auroral oval, there's mid + hi lat aurora tonight.

Beautiful sky earlier. :)

Soup de jour, I've seen some weird anomalies in the THEMIS data for days with 7+ magnitude quakes, but I'm not sure if it's the positioning or not.

Since THEMIS studies the magnetic field, I was wondering how this process could work and the only reasonable hypothesis I could come up with is that maybe the magnetic fields transport piezoseismic energy or something up into the ionosphere, kinda like that terrestrial gamma ray flash + lightning release by NASA a few weeks ago - but this will take a while to study and I don't have the time right now.

And yes this is how the process works. We call it the rubber band effect. :)

HAARP magnetometers are offline.. again.

Interesting storm here in Alaska... eh? [link to radar.weather.gov]

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 046 Issued at 2200Z on 15 Feb 2010

IA. Analysis of Solar Active Regions and Activity from 14/2100Z
to 15/2100Z: Solar activity was low. Region 1048 (N21E50) produced a
low-level C-class flare early in the period. Region 1046 (N24W36)
continued to gradually decay. No new regions were numbered.

IB. Solar Activity Forecast: Solar activity is expected to be low
during the period with a chance for an isolated M-class flare from
Region 1048.

IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z:
Geomagnetic field activity ranged from quiet to active levels. ACE
solar wind data indicated an interplanetary shock passage at
approximately 15/1725Z. This was followed by a weak geomagnetic
sudden impulse at 15/1832Z (02 nT, Boulder USGS magnetometer). The
shock was likely associated with the M8/CME event of 12 February.

IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (16 -
17 February) with a chance for active levels. Activity is expected
to decrease to quiet levels on day 3 (18 February).

3-day Solar-Geophysical Forecast issued Feb 15 22:00 UTC

Maybe the solar wind clearing out the bulk of the particles caused the apparent "thinning"..
