The sun has unleashed three intense solar flares in just two days -- each
one stronger than the last -- in an unexpected uptick in solar activity.
The flares began on Sunday (April 2), when the sun fired off a moderate,
M5.3-class solar flare. A stronger, M5.7 solar flare followed later that
same day. Then, today (April 3), the sun erupted with an M5.8 flare. NASA's
Solar Dynamics Observatory spacecraft captured video of the flares as they
occurred.

Are UFO's Interrupting Your Radio and TV?

HOUSTON -- In countless paranormal shows including The X-Files, whenever a
UFO is about to get you -- hovering over your car or house -- the first
symptom is that the radio goes haywire and stations you were once
receiving, start to fuzz-out in a static melee. Then, various other
automotive and home electronics start flashing in and out, before total
failure preceding the inevitable light shaft. Culturally, we've been primed
to be creeped out whenever any of these symptoms show. Many of us driving
around town had hairs raised on the back of the neck as it was discovered
normally clear FM radio stations on the lower end (87FM to 93FM) and the
higher end (104FM-108FM) were suddenly tough to tune-in. Some TV viewers
using an antenna had trouble pulling in a reliable signal from normally
strong stations. This effect seemed to happen most between about 1am and
5am. It was no fault of your TV or radio -- or the transmitters -- and it
likely wasn't aliens. It was an observed and measurable phenomena
called, "temperature inversion." Normally it's hotter at the ground that in
the sky. Many times however, on clear nights, the ground cools faster than
the air high above. This creates an inverted temperature profile, where
it's actually warmer above the ground then at the surface. That setup traps
pollution making for poor air quality, and if strong enough, can bounce
radio signals due to density changes. Cool air has a higher density than
warm air, so as signals were broadcast from the tops of towers in the warm
area, the transmissions would, "bounce off" of the cooler air below and go
back out to the sky. Short-wave radio and ham enthusiasts can tell you
under these special conditions you can actually transmit much farther than
normal, and receive signals from far-away continents you wouldn't normally
be able. But for local viewers and listeners, it's not a, "good thing"
because it makes it hard, if not impossible, to get your channels.
