populated sun

There are changes in the solar face: isolated AR4343, at right, is fading as quickly as it grew some days ago; on the other front, a big spot, AR4349, has just emerged from behind the eastern limb and began its 2-week trip across the face. The solar wind speed is very high, above 1.000 km/s; besides, a geomagnetic storm can be expected as reported in this section.
