Oggi 7 novembre 2017 l’ Europa è stata investita da una nuova tempesta geomagnetica di carattere minore rispetto alle precedenti del 31 agosto e 6-8 di settembre, vedi qui:
Tempesta geomagnetica del 31/8 – 2/9: http://www.solaractivity.it/2017/09/analisi-geomagnetica-2017-09-02/
Tempesta geomagnetica del 6/9 – 8/9: http://www.solaractivity.it/2017/09/analisi-geomagnetica-2017-09-08/
Nonostante questo l’ indice geomagnetico DST si è spostato di un differenziale notevole: da +30 nT a -45 nT con un differenziale complessivo di -75 nT.
Questa cosa ha provocato una tempesta geomagnetica di classe G1
Ricordiamo che tutta l’ energia ricevuta dal 31 agosto al 2 settembre e quella ricevuta poi il 6-8 di settembre non si è ancora dissipata. E ricordiamo che fino a ieri l’ Europa e tutto il pianeta sono stati scossi da fenomeni importanti e ripetuti. Vedi l’ esempio qui sotto relativo a solo l’ ultima settimana.
Europa, ultimi 7 giorni
Mondo, ultimi 7 giorni
Pertanto questo accumulo ulteriore potrebbe scatenare fenomeni sisimici importanti ed improvvisi con un mix di fenomeni profondi (dovuti alle precendenti tempeste) e fenomeni entro i 10 km di profondità dovuti a queste nuove perturbazioni.
Aggiungiamo che nelle ultime ore si sta notando un incremento dell’ attività nella banda dei raggi X e questo potrebbe voler significare che il Sole si sta preparando a sparare contro di noi uno dei suoi potenti flare.
Sicuramente l’ Europa sta attraversando un periodo geomagnetico delicato da tenere in grande considerazione.
Update 07/11/2017 21:49 UTC
Situazione in rapida evoluzione. L’allerta viene esteso a tutto il pianeta dato che la perturbazione geomagnetica si è estesa. Zone particolarmente colpite saranno le americhe e il Pacifico, oltre, si intende, all’ Europa.
Segnaliamo il 6.6 a 113 km (media) di profondità appena avvenuto in Papua Nuova Guinea.
Magnitude Mw 6.5
Region NEW GUINEA, PAPUA NEW GUINEA
Date time 2017-11-07 21:26:39.1 UTC
Location 4.17 S ; 143.49 E
Depth 122 km
Segnaliamo inoltre un sisma molto particolare avvenuto molto vicino al supervulcano di Yellowstone il giorno 5 novembre e passato quasi del tutto inosservato ai media.
Magnitude ML 3.5
Region SOUTHERN IDAHO
Date time 2017-11-05 19:58:11.5 UTC
Location 42.58 N ; 111.42 W
Depth 8 km
Update 08/11/2017 15:32 UTC
Secondo giorno consecutivo di tempesta solare che per diverse ore ha toccato la classe G2 Planetaria. Ieri e oggi su Europa una G1.
Indice DST come si vede in piacchiata ha sfondato più volte la soglia dei -50 nT. raggiungendo anche -70 nT.
Sismi dal 7 novembre fino al 21 dicembre 2017.
