... A distance-limited sample of southern Wolf-Rayet stars within 3 kpc of the Sun has been observed with the Australia Telescope Compact Array at 8.64 GHz and 4.80 GHz. ... Five sources are classified as non-thermal. ... We derive mass-loss rates for the thermal sources. After combining them with all existing radio mass-loss rates of Wolf-Rayet stars in the northern and southern hemisphere, we perform a comparison with mass-loss rates derived from optical emission lines. ...

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ... The belt of activity is one of the primary concepts, characterizing the solar cycle. ...
