Little teensy-weensy sub-atomic particles.
Haha, just joking whiteangel...things are getting interesting in geospace, too. Here's NOAA's SW Forecast-
Solar Wind.
24 hr Summary...The high speed stream that began late yesterday remained in effect.
During the period, solar wind speed at ACE rose from around 400 km/s to
end in the upper 400 to lower 500 km/s range. Bz varied between +/- 10
nT and total field reached about 12 nT during the onset of the high
speed stream. By the end of the day, Bz had settled to +/- 5 nT and
total field has diminished to about 5 nT. The solar sector orientation
was generally toward (negative) with the exception of a brief excursion
into the positive sector between 02/1500-1600 UTC. ACE spacecraft data
indicated the low energy particle flux was still rising at the time of
this report indicating the CME had not yet arrived.
.Forecast...Solar wind speed is expected to remain enhanced through the forecast
period.
The current equatorial coronal hole is expected to be followed
shortly by a negative polarity northern hemisphere coronal hole. The
solar wind will further be complicated by the expected arrival on day 1
(03 Feb) of a glancing blow from the 31 January CME. [
