# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A small Fast Forward shock in the solar wind was detected today
(27-Sep-2019) at 04:50 UT. The magnetic field jumped from 1 to 4 nT and the
solar wind speed from 340 km/s to 370 km/s. The origin is not clear, and
the relatively small size of the jump had no consequence on the K/Kp levels
at Earth.
