... The Sun is the closest star to us, and a regular object in our Galaxy. Solar activity manifests itself, primarily, in solar flares - episodic explosive energy release in the form of electromagnetic radiation and high energy particles (electrons and protons). The nature of the flares is related to cyclic variations of global and local magnetic fields in the atmosphere of the Sun. ... Such formations are called active regions. ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

... The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade - reaching a mid-summer low and falling into yet another state of "hibernation". Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. ... The first low lasted 51 days, from 21 July until 11 September last year. ... Now, almost a year later, it seems the Sun has hit a new low almost as "deep" as the first. ...
