# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
As expected, the arrival of 14th July full halo coronal mass ejection (CME)
earlier today  and subsequent strong variations of solar wind parameters
have created a strong geomagnetic disturbance. Kp index reached moderate
storm levels (Kp=6), while local index at Dourbes reached minor storm level
K = 5, during 12 UT - 15UT.

Solar wind speed is currently (16th July, 16:00 UT) 500 km/s, total
interplanetary magnetic field is 19.8 nT, while Bz is slightly increased
from -23 nT (at 10:30 UT) till -11 nT now.

The geo-environment is expected to remain at storming level for the next
several hours due to the observed continuous negative interval of Bz.
Maximum possible value of Kp index is 7, the strongest predicted value of
the Dst index is -120.
