Rare clouds:

Clouds Crashing Over Nebraska

Storm chaser Alex Schueth captured timelapse of a rare cloud formation called undulatus asperatus during a storm over Lincoln, Nebraska. The term translates to “roughed or agitated waves.” It describes a bizarre rolling pattern that gives the impression of being underwater looking up at the surface at waves. Margaret LeMone, a cloud expert with the National Center for Atmospheric Research has taken photos of asperatus clouds for 30 years, and considers it a likely new cloud type.

Like roiling, airborne waves. Spectacular.

UC Berkeley’s Early Warning System Beat Napa Earthquake by 10 Seconds
Ten seconds before the San Francisco Bay Area started shaking early Sunday morning, an experimental system in a UC Berkeley lab sounded an alarm, counting down to the impending earthquake. The system works through an array of sensors near the fault line which calculate the severity of the quake and broadcast a warning.
It might not seem like much, but even a few seconds notice could allow utilities to shut off gas lines, elevators to let people off at the next floor, and trains to slow down. The USGS cites the benefits a warning could give to a doctor in the middle of performing surgery. In 2012, BART adopted an automatic braking system linked to the program, called Shake Alert.

What was over Atlanta this morning?

“Undulatus asperatus” clouds.

Cause? Gravity wave packet.

According to Wikipedia:

"Undulatus asperatus (or alternately, asperatus) is a cloud formation, proposed in 2009 as a separate cloud classification by the founder of the Cloud Appreciation Society. If successful it will be the first cloud formation added since cirrus intortus in 1951 to the International Cloud Atlas of the World Meteorological Organization."

Coronal Mass Ejection as viewed by the Solar Dynamics Observatory

The Sun unleashed an M-2 (medium-sized) solar flare, an S1-class (minor) radiation storm and a spectacular coronal mass ejection (CME) on June 7, 2011 from sunspot complex 1226-1227. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface.
