3 ÍNDEX KP
Tranquil, No Tempesta geomagnètica
ÍNDEX PLANETARI KP
5 ÍNDEX A
Tranquil, No Tempesta
No Radio Aurora
ÍNDEX KP figure provides a good indicator of viewing the Aurora Borealis or Northern Lights The greater the KP-Index the higher probability of viewing. The Estimated 3-hour Planetary Kp-index data is collected from ground-based magnetometers.
ÍNDEX A is an indicator of possible enhanced VHF radio signal communication at a range of upto 1000 miles or more. During strong solar activity frequencies from 28 to 433MHZ or higher allowing radio communications to be possible at mid to high latitudes .
