Aggiornamento mattutino:

purtroppo sembra molto debole il passaggio...

in ogni caso unitamente al coronal hole (e all'aumento temporaneo del vento solare) qualche effetto dovrebbe darlo.

eventuali "anomalie" si dovrebbero verificare già in GFS 12h ... maggiore rinforzo del blocking e rafforzamento dei centri motori...I hope!

February 15, 2018 @ 10:20 UTCWeak Shock PassageWhat appears to be a weak shock passage was detected at 07:51 UTC by the DSCOVR spacecraft. This is likely related to the CME from February 12th. A further solar wind increase is still expected as a coronal hole stream should become geoeffective over the next few days. Visible aurora will be possible at higher latitudes.
