tra il 24 e 25 giugno c'e' stata una cme , espulsione di massa coronale abbastanza intensa che potrebbe portare
nei successivi giorni ad aurore boreali nelle basse latitudini del nord Europa e nord America, basse latitudini perche'
in questo periodo del sole di mezzanotte, il sole, sopra il circolo polare artico non tramonta mai.
Il 28 e 29 giugno sono previste intense attività solarei con tempesta geomagnetica di classe G1 KP5

A. NOAA Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Jun 28-Jun 30 2024 is 4.67 (NOAA Scale
G1).

Rationale: G1 (Minor) geomagnetic storming is likely on 28-29 Jun due to
CME arrivals from the event that left the Sun on 24 Jun.
