NASA'S GIANT SPACE BALLOON: On May 17th, NASA successfully launched a gigantic
helium balloon from Wanaka, New Zealand, on a 100+ day mission to the
stratosphere. The 19 million cubic foot behemoth is now floating over southern
Australia, and it will soon proceed to circumnavigate the southern
hemisphere.  Sky watchers near the flight path can see the "space balloon"
with the unaided eye and track it with backyard telescopes. Visit
http://spaceweather.com for observing tips and more information about the
balloon's fascinating payload.
 
MINOR GEOMAGNETIC STORMS POSSIBLE THIS WEEK: NOAA forecasters estimate a 50%
to 60% chance of minor G1-class geomagnetic storms on May 19-20 when Earth
enters a stream of high-speed solar wind. High-latitude sky watchers should be
alert for auroras, especially in the southern hemisphere where darkening
autumn skies favor visibility.
