Todays sun data

Latest EIT-304 image // Sun images from NASA

Flux index:69
Spot number:12
X-Ray index:*
A index:7
Kp index:2
 
Conditions 00-10MHz:Fair
Conditions 10-20MHz:Poor
Conditions 20-30MHz:Closed
We are working on the algorithm, conditions shown here may not correlate with real conditions.
The best check is always to power up your HF rig and listen on every band to be sure!
