1ª LABAREDA SOLAR DE 2013 & HISTÓRICO .



We are now in period called Solar Cycle 24 which started in January 8, 2008 and it is the 24th solar cycle since 1755, when recording of solar sunspot activity began. The solar cycle is the periodic change in Sun’s activity (including changes in the levels of solar radiation and ejection of solar material) and appearance visible in changes in the number of sunspots, flares, and other visible manifestations. Solar cycles have a duration of about 11 years. NASA predicts that solar cycle 24 will peak in early or mid 2013 with about 59 sunspots. This would make it the least active cycle in the past one...

Before 1979, there were less than a dozen known sungrazing comets. As of December 2012, we know of 2,500. Why did this number increase? With solar observatories like SOHO, STEREO, and SDO, we have not only better means of viewing the sun, but also the comets that approach it. SOHO allows us to see smaller, fainter comets closer to the sun than we have ever been able to see before. Even though many of these comets do not survive their journey past the sun, they survive long enough to be observed, and be added to our record of sungrazing comets....

The following images are compilations of the best anomalies found from the SOHO probe by SolarWatcher.   SOHO, the Solar & Heliospheric Observatory, is a project of international collaboration between ESA and NASA to study the Sun from its deep core to the outer corona and the solar wind. SOHO was launched on December 2, 1995. The SOHO spacecraft was built in Europe by an industry team led by prime contractor Matra Marconi Space (now EADS Astrium) under overall management by ESA. The twelve instruments on board SOHO were provided by European and American scientists. SOHO’s Greatest Hits Playlist Music...
