Solar Update from SolarCycle

Solar Update – Solar activity remains low but that could change should two new sunspot regions continue to grow. One of these regions is located in the northern hemisphere and is now the size of atleast 3 planet earths across. Another region is now rotating into view on the southeast limb. The sun currently has 5 visible sunspot groups. There is a chance for C-Class flares.

Antimatter From Thunderstorms!

January 13, 2011 1 comment

Jan. 11, 2011: Scientists using NASA’s Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before.

Scientists think the antimatter particles were formed inside thunderstorms in a terrestrial gamma-ray flash (TGF) associated with lightning. It is estimated that about 500 TGFs occur daily worldwide, but most go undetected.

Sunspot 1035 Reborn

From Old and decaying sunspot 1035, declared to be “a corpse” just yesterday, is showing signs of renewed life. Pete Lawrence sends this picture from his backyard observatory in Selsey, UK:

“A welcome view of the sun on a cold January day reveals the remains of AR11035 still alive and kicking,” says Lawrence. Beneath the waving filaments and bright magnetic froth (“plage”), a dark core is coelescing in the heart of the active region. That makes it a genuine sunspot again. NOAA has re-numbered the region “1040,

Sunspots Continue


Sunspot 1039 is about to disappear over the sun’s western limb, but the sun won’t remain blank for long. Another active region is approaching from the east, shown here in a Jan. 5th image from the Solar and Heliospheric Observatory:

The approaching region is old sunspot 1035. It has been transiting the far side of the sun since Dec. 20th.

Sunspot 1039 Active


Sunspot 1039 is putting on a good show for amateur astronomers. “The active region sizzled and popped as I photographed it on Dec. 31st,” reports Michael Buxton of Ocean Beach, California. Click on the image to view two hours of action:

“It is quite interesting to watch as energy surges and swirls around the sunspot’s dark cores,” he says.

2010 appears to be picking up where 2009 left off–with sunspot activity on the rise.

Lets hope the increased sunspot activitiy continues to improve radio propogation.


Ever Increasing Sunspot Activity

December 31, 2009 Leave a comment

Solar Cycle 24 could hold some surprises yet.

Sunspot activity is on the increase.

December 30 forecast from the U.S. Air Force predicts a solar flux value of 79 from December 31 to January 3, 80 for January 4-9, and 85 for January 10-18. They also predict a steady and stable planetary A index of five through February 13. Geophysical Institute Prague predicts quiet for the first week of January. You can get an update on the Air Force/NOAA prediction after 2100 UTC at, Since December 26 we’ve been blessed with new sunspot group 1039, which is now just past the zero degree meridian, referenced to Earth. This is the spot in the center of the solar image. This is the sixth new sunspot group to emerge in December. After today we will know the three-month moving daily sunspot average centered on November, and it looks close to the average centered on August, 2007, which was 10.17. The moving average has not been above ten since then. The daily average for the month of December should be close to 15.7, the highest monthly average since March, 2008.
