Solar Radiation Storm and CME

These colorful solar animations are always very interesting to me. Click animation below to view full-sized version.

From SpaceWeather.com:

A radiation storm that began on Nov. 26th when a magnetic filament erupted on the sun is subsiding. Nevertheless, the Earth-effects are just beginning. The same explosion that caused the radiation storm also hurled a CME into space at about 930 km/s (2 million mph). According to analysts at the Goddard Space Weather Lab, the CME will reach our planet on Nov. 28th at 17:21 UT (+/- 7 hours).

Solar Plasma Flow

This video compresses about an hour of solar activity around a sunspot to a little over ten seconds.

Via APOD:

The Sun’s surface keeps changing. The above movie shows how the Sun’s surface oozes during a single hour. The Sun’s photosphere has thousands of bumps called granules and usually a few dark depressions called sunspots.

Flash Flood Gauge

flood-gauge.jpgI took this image going through the bottom of a wash just north of US 60 in Wickenburg, AZ. The desert town has lots of washes that eventually flow toward the Hassayampa River.

This APS pole has a flood depth gauge painted on it scaled in feet. At the top of the hill before you drive into the wash there is a warning sign posted by the town that says:

“WHEN FLOODED TURN AROUND – DON’T DROWN.”

We have yet to see a gully-washer since we moved here last year. It would be interesting to see this wash during a flash flood but we’ll curb our curiosity and try to stay home when the monsoons come around.
