A WebSDR is a Software-Defined Radio receiver connected to the Internet, allowing many users to listen and tune it simultaneously.
SDR technology makes it possible for all listeners to tune independently, and thus listen to different signals; this is in contrast to the older Internet connected receivers that can only be tuned by one person.
The WebSDR.org site lists Internet SDR receivers all over the world that you can use. If you ever wondered what your 40m signal sounds like in Atlanta then tune in one of the SDR's listed at http://www.websdr.org/

The Sun is becoming more active again
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).
