# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
The high speed stream from the equatorial extension of the southern coronal
hole has arrived to the Earth earlier than expected and caused minor storm
both locally and at planetary levels overnight (together with the ICME
glancing blow described in the previous PRESTO). Major storm periods (with
isolated severe periods) can be expected in the next 24 h as the solar wind
speed is at 730 km/s with interplanetary magnetic fields of 9 nT.
