ACTIVE SUNSPOT: A sunspot, currently located on the farside of the sun, is about to emerge over the sun's southeastern limb. It is crackling with M-class solar flares and could bring a significant uptick in solar activity. Solar flare alerts: text, voice.
GEOMAGNETIC ACTIVITY CONTINUES: For the third day in a row, geomagnetic storms are circling the poles. In North America, auroras have spilled across the Canadian border descending as far south as Utah, Colorado, Kansas, and Nebraska. The best place to see the show, according to pilot Matt Melnyk, is from the window of an airplane:
"I photographed an unbelievable display from the cockpit at 21,000 feet while flying across Alberta Canada," says Melnyk. "Being the pilot we get a front row view of the amazing aurora and this display was nothing less than spectacular!"
The storms were instigated by a CME strike on Oct. 8th and they are about to be re-energized by a solar wind stream due to hit Earth's magnetic field on Oct. 10th. NOAA forecasters estimate a 40% chance of strong geomagnetic storms during the next 24 hours, so high-latitude sky watchers should remain alert for auroras. Aurora alerts: text, voice.
DRAGON AND THE ISS: Laden with supplies, SpaceX's Dragon spacecraft is approaching the International Space Station for docking on Wednesday, Oct. 10th. Last night, David Blanchard saw the commercial spacecraft chasing the ISS across the sky above Flagstaff, Arizona:
"The Dragon capsule raced to catch the ISS as the pair moved across the western sky separated by about 20 seconds," says Blanhard. "This image is a single 30-s exposure that shows the separation and how Dragon trails ISS."
On Wednesday, these two streaks will merge. As the Dragon approaches the ISS, astronaut and station commander Suni Williams will reach out with the station's robot arm to grapple the capsule. The spacecraft will then be joined to one of the station's ports where astronauts will unload its 1,000 pounds of food, clothing, science gear and other items. Later, the astronauts will load almost 2,000 pounds of used equipment and experiments into the Dragon to be returned to Earth safely in about three weeks.

Other White Object next to the Sun
Does anyone see the 2nd object next to the Sun?
Brown Dwarf?
Secondly, the sun is supposed to be Yellow!!!!
This thing is super bright white!
I think this is a clear sign of the sun changing.
Maybe I'm missing something here.
Sun still the same color....
The sun looks white because that is the exposure on the settings of the camera! it allows scientist to better analyze the sun, other wise the sun would be too bright and they couldnt see it... Check out this website it has other types of exposures and feeds from the sun.

How bout that object
Thanks for that! I was wondering...
How about that object though? Next to the sun...
Very interesting!
