Zelo zanimivo pisanje od danes na

"OLD" SOLAR ACTIVITY: This week, three big sunspots are crossing the face of the sun and on March 25th one of them (989) produced a strong M-class solar flare. Many readers have asked, is this the new solar cycle? No, it's the old one. Although Solar Cycle 24 has begun, these are not Cycle 24 spots. Their magnetic polarity associates them with old Cycle 23:
The magnetic map, above, was made by the Solar and Heliospheric Observatory (SOHO) just this morning. It shows the north and south magnetic poles of the three sunspots. All are oriented according to the patterns of Solar Cycle 23. Cycle 24 spots would be reversed.
What's going on? We have two solar cycles active at the same time. Solar Cycle 24 has begun, but Solar Cycle 23 has not ended. This is perfectly normal. Around the time of solar minimum--i.e., now--old-cycle spots and new-cycle spots frequently intermingle. Eventually Cycle 23 will fade to zero, but not yet.
