16音符の練習録音です。16音符が何度も出て来ます(20回(^_^;))。
この曲はきれいなメロディなので何とかクリアしたいです。(^^♪

The solar sphere as observed by STEREO and the Solar Dynamics Observatory on January 31, 2011. Because the STEREO separation was still slightly less than 180o at that time, a narrow gap on the far side of the Sun has been interpolated to simulate the full 360o view. The gap and quality of farside imaging will improve even more in the days and weeks ahead.
"This is a big moment in solar physics," says Vourlidas. "STEREO has revealed the sun as it really is--a sphere of hot plasma and intricately woven magnetic fields."
Each STEREO probe photographs half of the star and beams the images to Earth. Researchers combine the two views to create a sphere. These aren't just regular pictures, however. STEREO's telescopes are tuned to four wavelengths of extreme ultraviolet radiation selected to trace key aspects of solar activity such as flares, tsunamis and magnetic filaments. Nothing escapes their attention.

"I expect great advances in theoretical solar physics and space weather forecasting."
Consider the following: In the past, an active sunspot could emerge on the far side of the sun completely hidden from Earth. Then, the sun's rotation could turn that region toward our planet, spitting flares and clouds of plasma, with little warning.
"Not anymore," says Bill Murtagh, a senior forecaster at NOAA's Space Weather Prediction Center in Boulder, Colorado. "Farside active regions can no longer take us by surprise. Thanks to STEREO, we know they're coming."
NOAA is already using 3D STEREO models of CMEs (billion-ton clouds of plasma ejected by the sun) to improve space weather forecasts for airlines, power companies, satellite operators, and other customers. The full sun view should improve those forecasts even more.
