CORONAL HOLE: A large "coronal hole" has formed in the atmosphere above the sun's northern hemisphere, and it is spewing solar wind into space. NASA's Solar Dynamics Observatory took this picture of the UV-dark gap during the early hours of June 19th:
Coronal holes are places where the sun's magnetic field opens up and allows the solar wind to escape. A wide stream of plasma flowing from this particular coronal hole will reach Earth, and brush against our planet's magnetic field, on June 23-24. High-latitude sky watchers should be alert for auroras on those dates. Aurora alerts:

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.
