The first event is considered to be the earliest Arabian recorded event of aurora. The second and third events confirmed the case of strong solar activity during the end of the 12th century and mid 15th century, respectively. The fourth event was around solar maximum activity in 1449 AD. So, these records could be considered as proxies for intense geomagnetic solar storms, during early solar activities.  Journal Name : SOLAR PHYSICS  Volume : 225  Issue Number : 1  Publishing Year : 2004 AH   Added Date : Saturday, June 14, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email حسن بن محمد باصرة   Researcher   hbasurah@hotmail.com Back To Researches Page
