Re: Terry's Astronomy Thread.
Daily Suspicious0bserver's Weather Post:
September 29, 2014 What's in the sky tonight? September 29, 2014 -There are now four sunspot groups on the solar disk with unstable magnetic fields, which means an eruption today is likely. NOAA forecasters have raised the daily odds of an M-class solar flare to 75% and an X-flare to 15%. -While much attention is being paid to the fact that September's equinox kicked off aurora season in the Northern Hemisphere, we should not forget that the Southern Hemisphere has just experienced the exact same equinox. It is aurora season there, too. Petr Horįlek sends this example of Southern Lights over Lauder, New Zealand, on Sept 25th. "The auroras burned very low above the southern horizon here at the NIWA atmospheric research station," Horįlek says. "The opened dome is the BOOTES telescope, which is used to detect the optical afterglow of distant gamma-ray bursts. A green lidar behind me reflected from the dome, giving it a green hue." For reasons researchers do not fully understand, at this time of year even gentle gusts of solar wind can ignite beautiful auroras. Right now Earth is passing through a minor stream of solar wind that has both poles aglow. Astro Picture of the Day: September 29, 2014 How did these Martian rocks form? As the robotic Curiosity rover has approached Pahrump Hills on Mars, it has seen an interesting and textured landscape dotted by some unusual rocks. The featured image shows a curiously round rock spanning about two centimeters across. Seemingly a larger version of numerous spherules dubbed blueberries found by the Opportunity rover on Mars in 2004, what caused this roundness remains unknown. Possibilities include frequent tumbling in flowing water, sprayed molten rock in a volcanic eruption, or a concretion mechanism. The inset image, taken a few days later, shows another small but unusually shaped rock structure. As Curiosity rolls around and up Mount Sharp, different layers of the landscape will be imaged and studied to better understand the ancient history of the region and to investigate whether Mars could once have harbored life.
