A large sunspot group is rotating over the sun’s northeastern limb, possibly signaling an uptick in solar activity. Measuring some 40,000 km wide and at least twice that in length, the behemoth active region is an easy target for backyard solar
The solar wind was at increased levels Tuesday morning and combined with a south tilting Bz, it stirred up a minor geomagnetic storm at high latitudes. Things have since returned to quieter levels.Solar activity increased to moderate levels Monday with three M-Class
An M1.1 Solar Flare peaked at 15:08 UTC Monday morning and was centered around a new region located on the Northeast Limb. Stay Tuned for increasing solar activity.The second and third M-Class Flares of the day has taken place around the new region hiding on the
Science has only just begun to understand how cyclical changes in the Sun effect Earth’s weather and climate. But the more technological human society grows, the more vulnerable we may become.Activity on the Sun is due to reach its peak around early 2014, so expect
The intense geomagnetic storm of Oct. 24-25 (described below) has subsided and US skies are returning to normal. If you missed the show, don’t worry. The Northern Lights will be back. For much of the past few years, the sun has been in a quiet state; but solar activity
UPDATE (2011-10-25, 14:10):Many observers, especially in the deep south, commented on the pure red color of the lights they saw. These rare all-red auroras sometimes appear during intense geomagnetic storms. They occur some 300 to 500 km above Earth’s surface and
A bright CME blasted off the sun on Oct. 22nd, and it appears to be heading for Mars. Analysts at the Goddard Space Weather Lab expect the cloud to reach the Red Planet on Oct. 26th (forecast track). A brief discussion of what CMEs can do to Mars follows this SOHO
A significant CME blasted off the sun today, Oct. 22nd, around 1100 UT. Analysts at the Goddard Space Weather Lab say the cloud is heading for Mars, due to hit the Red Planet on Oct. 26th. (movie, forecast track)While looking at the latest STEREO Ahead images,
The official Sunspot number for Oct 21,2011 is 207. This is a new record for Solar Cycle 24. Despite the amount of Sunspots, only low level M-Class flares have taken place thus far. This could soon change. Solar activity has been moderate with low level
The massive ROSAT X-ray space telescope is making its final spiralling orbits around Earth. Most experts agree that re-entry will occur during the early hours of Oct. 23rd over a still-unknown region of our planet. Meanwhile, the satellite can still be seen slicing
