TODAYS SUN DATA AND HF PROPAGATION
Todays sun data

Latest EIT-304 image // Sun images from NASA

Flux index:95
Spot number:24
X-Ray index:B2.0
A index:6
Kp index:2
 
Conditions 00-10MHz:Poor
Conditions 10-20MHz:Poor
Conditions 20-30MHz:Very Poor
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!
