EARTH THROUGH THE RINGS OF SATURN: One month from now, on July 19th, NASA's Cassini spacecraft will photograph Earth from Saturn. The unprecedented image will show the "Pale Blue Dot" in natural color, as it would appear to the human eye, framed by the rings of another world. Get the full story from Science@NASA.

INCREASING CHANCE OF FLARES: The magnetic field of sunspot AR1775 is growing more complex, increasing the chance of an eruption. NOAA forecasters estimate a 20% chance of solar flares on June 19th.
FARSIDE ACTIVE REGION: Meanwhile on the farside of the sun, an un-numbered active region is seething with activity, and appears capable of significant eruptions. NASA's STEREO-Behind spacecraft is stationed over the sun's east limb with a good view of the hot spot (circled):
During the early hours of June 18th, a long-duration flare from this active region hurled a coronal mass ejection (CME) over the sun's eastern limb. However, none of the rocky planets (Mercury, Venus, Earth, Mars) were in the line of fire.
In a few days, the sun's rotation will carry the active region around the eastern limb and onto the Earthside of the sun. Then we will have a direct view of the underlying sunspot group and be able to better assess its potential for future flares. Stay tuned.
Monitor the farside: You can see an animation of today's flare and monitor the active region in the days ahead by downloading NASA's Interplanetary 3D Sun app. It works on high-end iPhones (4s and 5), iPad 2s, and mini-iPads.
NOONTIME ECLIPSE: Consider it a solar eclipse ... of Jupiter. On June 19th the sun will pass directly in front of Jupiter, completely eclipsing the giant planet. Coronagraphs onboard the Solar and Heliospheric Observatory are monitoring the convergence:
The CME in the movie was blasted into space by a farside active region described in today's lead news item. Jupiter appears to be in the line of fire, but it is not. The cloud is merely passing in front of the planet; even the CMEs are eclipsing Jupiter today. Updated images of the "eclipse" may be found at the SOHO Realtime Images web page.

SLIGHT CHANCE OF FLARES: There are 7 sunspot groups on the Earthside of the sun, but none has a complex magnetic field that harbors energy for strong eruptions. NOAA forecasters estimate a 10% chance of M-class flares and no more than a 1% chance of X-class flares on June 17th.
SOUTHERN SUNSPOTS: So far, Solar Cycle 24 has been lopsided. Sunspots north of the sun's equator have outnumbered sunspots to the south by a significant margin: data. But now the southern hemisphere is catching up. Today a raft of southern sunspots is rotating over the sun's eastern limb:
Solar physicist and sunspot forecaster Dean Pesnell of the Goddard Space Flight Center believes Solar Cycle 24 is likely double-peaked. A surge in southern sunspots could herald the second peak, due in late 2013 or early 2014. This solar cycle has been fairly anemic so far, so it could use a boost; the sun's southern hemisphere could be poised to provide it. Solar flare alerts:textvoice
On June14th high school students in Bishop, California, launched their seventh "space weather balloon." Its mission: To investigate the effect of solar flares and radiation storms on Earth's ozone layer. 's mentor, Dr. Tony Phillips, photographed the balloon moments before liftoff from their "Edge of Space Port" in the Sierra Nevada mountains:
The balloon's payload carried two cameras, an ozone sensor, a cryogenic thermometer, and a GPS altimeter to an altitude of 110,000 feet above Earth's surface. All of the payload's core space weather instrumentation was built by the students themselves. After the balloon popped, as planned, the payload parachuted back to Earth, landing near the ancient Bristlecone Pine Forest in California's White Mountains. A recovery team has already retrieved the payload, and students are inspecting the data now.
The students launched the balloon on June 14th, a period of low solar activity, because they wanted to compare quiet sun data with a similar data set they collected on May 22nd during a strong solar radiation storm. Stay tuned for their results!

SPACE STATION 3D: On June 15th, the International Space Station flew directly above Saint Rémy lès Chevreuse, France. Amateur astronomer Sylvain Weiller trained his telescope on the bright, fast-moving speck of light and recorded a high-res movie of the passing spaceship. Click on the image below--and cross your eyes to see the flyby in 3D:
"To capture a high resolution movie of the ISS, everything must be okay--the weather, the seeing, the scope and mount, an overhead pass, yourself, the PCs and a bit of luck!" says Weiller. "This was the case for me on the evening of June 15. The full story of my lucky observing session and additional movies may be found here."
Readers who wish to try their own luck with the ISS can turn their smartphone into a field-tested satellite tracker. Download Spaceweather.com's Satellite Flybys app and let the flybys begin.
