Product: documentation at http://www.sidc.be/products/presto
#--------------------------------------------------------------------#
# FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) #
#--------------------------------------------------------------------#
Note: There was an error on the date in the previous PRESTO, the
arrival of the ICME is 00:40 UT, on February 18 (not 17): An ICME has
arrived to the Earth. A shock was seen at ACE around 00:40 UT on
February 18, followed by strong interplanetary magnetic fields reaching
now 35 nT. Geomagnetic conditions are at present active (Kp=4). The
interplanetary magnetic field is mostly northward directed, but it may
turn south in the coming hours and produce stronger geomagnetic effects.
#--------------------------------------------------------------------#
是今天早上八时四十分到达.Kp指数达=4.
