SOHO Extreme ultraviolet Imaging Telescope (EIT) solar images last summer and today:

Solar activity is starting to increase again after what has been a relatively long quiet spell associated with the minimum part of the solar cycle. February was the first month in quite some time where there were sunspots every day of the month. In the image above from last July (left), the lone bright area below the equator near the center was not associated with a sunspot, but was in an area of magnetic activity.

Remember that the sun is a star, like all stars, whose business is to fuse lighter elements into heavier ones; our sun fuses hydrogen into helium. This process results in chaotic magnetic behavior of the solar plasma which fluctuates in intensity over an eleven year cycle. We wrote “Ultimate Global Warming - SPF 2 Million Won’t Be Enough” to describe the process.

Evidently, we’re on the upswing after what some scientists (real ones, not climate liars) say was a very extended inactive period, which some feared would put the sun into many years of minimal activity. It is likely that such an extended period, the Maunder Minimum, was the cause of the “Little Ice Age” during the 1600s and 1700s. We wrote “Correlating Sunspots to Global Climate” which illustrates the phenomenon using animations and graphics.

Personally, after the winter we have been having in North America this season, I will be glad to see the sunspots bring us back to our subtropical weather patterns. Old folks like warmer weather, y’know. C’mon global warming!

Diaz Lake is located in the Owens Valley, California, It has the distinction of having recently been formed as the result of a large earthquake. Click on the panoramic thumbnail for the full-sized version.

From Wikipedia:

Diaz Lake is located just south of Lone Pine, California, United States in Owens Valley. The lake was formed by the 1872 Lone Pine earthquake when 18 mi (29 km) of the Owens Valley dropped approximately 20 feet (6 m) and a new spring opened, causing water to fill the lowland.

The lake was named for the Diaz family who established a ranch here when brother Rafael and Eleuterio Diaz emigrated from Chile in the 1860’s. They owned and operated a successful cattle ranch until the land was sold to the city of Los Angeles.

Year-round fishing is available, and the “Diaz Lake Fish Derby” is held the first Saturday in March.

In this El Niño year, the snow levels dropped to below 5000 feet in the San Gabriels, normally not seen with snow on the southern slopes. Damsel took this image (cropped to make a panorama) after the rain passed the other day. Lingering clouds can be seen topping some of the peaks.

It looks like the solar activity is starting to increase. This is the first day in a while where there are three sunspots visible on the Earth-facing side of the sun. These images are from the SOHO spacecraft. The left panel is the visible light snapshot and the right panel is energy being emitted in a narrow band of ultraviolet. You can’t see UV, but it’s common knowledge that it is a major cause of skin damage.

Just how solar activity affects the climate isn’t well understood, but there is correlation between sunspot numbers and the climate.

I don’t know about you, but I am sure there are a lot of Americans rooting for warmer weather tonight. That includes us, even though we’re California weather wimps according to Breda.

While most of the east is enjoying the biggest blizzards in 90 years (so much for that global warming crap), we had a gentle rain last night which this Christmas cactus seemed to enjoy. Click on Damsel’s image to enlarge.

EXPLOSION ON THE SUN

Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) observed a bright double-ringed coronal mass ejection (CME) billowing over the sun’s western limb during the late hours of Feb. 1st. At present, the source of the blast is unknown.

The bright spot to the left of the sun is Venus. Click on the image for a slightly larger view.

Planet Gore posted an item today about wind turbine wake (’propwash’) causing turbines downwind to have reduced output because of the turbulent air generated by upwind turbines.

I have always been skeptical about the reliability, efficiency and cost-per-generated-kilowatt of wind turbines. We recently were on a road trip and saw two different convoys of trucks carrying the estimated fifty foot long blades either to a new installation or to maintenance. I couldn’t believe the way the immense turbine blades dwarfed the big-rig tractors hauling them.

From Popular Science.

Downstream wind turbines may lose 20 percent or even 30 percent of their power compared to their fellows in front, according to a study on wake effects at Horns Rev that MacKay highlights on his blog. The paper also emphasizes that different wind directions make it practically impossible to gauge an overall “steady state” for large wind farms, unless researchers can sample wind speeds and directions at multiple points throughout the array.

This shows that wind energy may represent a highly visible form of alternative energy, but certainly not one without its quirks and controversies. Still, better technology can squeeze more juice out of each gust, and cooperative energy-sharing efforts can help offset the fickle nature of wind power.
