[NZ4O Spaceweather] Sun Becoming More Active Again

[Thomas F. Giella NZ4O]

After an approximate two week slumber the sun is becoming active once again. The daily solar flux index rose to 91.0 on Friday May 27, 2011 after a minimum of 79.7 on Wednesday May 25, 2011. The daily sunspot number rose to 65 on Friday May 27, 2011 after a minimum of 23 on Tuesday May 24, 2011.

The number of sunspot groups is rising again with five visible numbered groups and one visible but as of yet un-numbered on Friday May 27, 2011.

New sunspot group #11226 located at S18E74 is growing rapidly in size and magnetic complexity and contains a twisted beta-gamma magnetic signature capable of producing M class solar flare and isolated X class solar flares. In the past 24 hour period the sunspot group has released five C class solar flares.

Recurrent transequatorial coronal hole #450 was in geo-effective (earth facing) position on May 24-25, 2011 and has impacted Earth's magnetic field in a negative manner with a maximum Kp of 6 (moderate geomagnetic storming conditions) and a maximum solar wind of ~550 (km/s).
