... Precisely one month ago, on 11 July 2009, the last active area of the new solar cycle disappeared from the surface of the Sun. Over the 30 days following this, neither observers on Earth nor devices in space have been able to detect the emergence of any sunspots. ... Therefore, it seems that our star has once again returned to a state of deep solar "winter", following several sparks of activity in May-June 2009. ... To date, this period has lasted 30 days. ...

Geomagnetic storms and substorms are a natural hazard similar to hurricanes, floods etc. ... Solar and geomagnetic activity also probably influences the Earth's climate and human health. ... Under southward directed IMF the Earth's magnetosphere is open to input from the solar wind flow. ... Since practical importance of solar wind measurements was recognized, a number of approaches was developed for prediction of the geomagnetic activity basing on the solar wind data. ...

... In summary, the available data consist of IUE UV (1200--3300A) spectra combined with ground-based optical spectra obtained with a matched aperture (10"x20"). ... REMARKS ABOUT THE IUE SPECTRA The IUE spectra consists of two segments obtained, respectively, with the short wavelength camera (SWS), covering the spectral range 1150-2000A at 5A spectral resolution, and the long-wavelenght camera (LWS), covering the spectral range 1900-3300A at 8A spectral resolution. ...

... 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. ...

. Distribution of Supernovae according to their parent galaxies' recession velocity. This graph shows the distribution of SNe according to the recession velocity of their parent galaxies. This graph is kept up to date till SN 2000ek . Along X-axis there are all velocity bands so that you have to read in this way: for example, the band on the graph marked as 2000 takes in all parent galaxies' recession velocities faster than 1000 until 2000 Km/sec.
