# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A shock was registered in situ in the solar wind data around 14:20 UTC on
November 17, possibly marking the anticipated glancing blow arrival of an
Interplanetary Coronal Mass Ejection (ICME), which lifted off the solar
surface 00:36 on November 04. The interplanetary magnetic field quickly
increased from 3 nT to 7 nT. The solar wind velocity increased from 380
km/s to almost 420 km/s. The solar wind density at the shock jumped from
7.5 ppcc to around 22.37 ppcc.
