Info transmitted every full 5 minutes	INFO 04 DEC 15 UTC KIEL K 3 3 = << NEXT EXPECTED KIEL K 6 6 >> = FORECASTS 04 DEC SUNACT ACTIVE MAGFIELD MAJOR STORM EXPECTED = 03 DEC R 11 11 FLUX 73 73 BOULDER A 7 7 = 03 DEC KIEL A 10 10 AR
Date, Time	actual date, end of last 3 hours = period of "k"-measurement
KIEL k	index k of the geomagnetic field, = measured at beacon
R	relative sunspot number = (SSN)
FLUX	solar flux at 10 cm wavelength, = measured at Penticton/Canada
BOULDER A	index A of the geomagnetic field, = measured at Boulder/Colorado
KIEL A	index A of the geomagnetic field, measu= red at beacon
SUNACT:	state of solar activity
only these expressions will be transmitted	- *quiet: less than 50% prob.of C-class = flares - eruptive: C-class flares expected = (probability higher 50%) - active: M-class flares expected - major flares expected: X-class flares = expected - proton flares expected* : (probability higher = 50%) - *warning condition: (activity levels exp. to = increase) - nil:* (end of alert = period)
MAGFIELD:	state of geomagnetic field
only these expressions will be transmitted	- *quiet* - *active conds expected: K > 4, A > 20 - minor storm expected: K > 5, A > 30 - major storm expected: K > 6, A > 50 - severe magstorm exp.: K > 7, A > 100 - magstorm in progress: K > 4, A > 30 - warning condition: activity levels exp. to = increase - nil*: end of warning = period
NA	not available

Range of KIEL k: 0 ... 9 / K = 9 => deviation > 500 nanoTesla
Range of BOULDER A and KIEL A: 0 ... 400
< next expected KIEL K n = n > will be transmitted only , if the current measurements will = bring the next "KIEL k" -figure to be higher than 5.
