~e; radar of lightning storms

["brian carroll" <human@electronetwork.org>]

of lightning:  tonight i was planning to write
a small piece on lightning after using the
weather-underground radar images to see that
severe thunderstorms were arriving, and how
these tools can be used together, digital
camera, radar maps, to visualize electro-
magnetic events such as lightning, which
even today retains many mysteries, such
as NASA astronauts seeing certain types
of lightning when orbiting the Earth that
were supposedly not possible to see given
theories at the time. here is a download
of a radar image that i find fascinating,
there are dozens of types of maps that can
be found online (i find mapping very useful
and it could be a way to visualize EM for
a larger audience, e.g. weather maps for
ultraviolet (UV) radiation, or geomagnetism,
or satellite imagery of clouds, light/heat).
the radar went down when i had the idea and
now the radar is back online with an image
of the passing storm with lightning in it...
