Members of the Washington County Amateur Radio Emergency Service teamed up
with the St. George Fire Department to install the new antenna on a 70-foot
flagpole. The antenna gives the Emergency Operations Center the ability to
communicate via direct radio waves with all of Utah and neighboring states
in the event of an emergency in which the Internet, cell phones and other
infrastructure-reliant systems are not available.

Scientists Discover Sun's 'Magnetic Heartbeat' Causes Solar Flares:

Scientists claim to have discovered a magnetic "solar heartbeat" in the
Sun's deep interior, that generates energy which leads to solar flares and
sunspots. Researchers developed a new supercomputer simulation to probe the
Sun's periodic magnetic field reversals. According to the model, every 40
years the Sun's zonal magnetic field bands switch their polarity.
Scientists say that cycle is about four times longer than the 11-year
sunspot cycle that governs the level of solar activity, 'SPACE.Com'
reported. The new study, led by the University of Montreal's Paul
Charbonneau, described that modelling the Sun has been a sticky problem for
decades. The first attempts in the 1980s captured only a rough
approximation of the turbulence inside of the Sun. Turbulence happens at
both large and small scales.
