Conduce Chile

Solar output goes through 11-year cycles, with high numbers of sunspots seen at their peak.

We are now at what should be the peak of what scientists call ‘Cycle 24’ – which is why last week’s solar storm resulted in sightings of the aurora borealis further south than usual. But sunspot numbers are running at less than half those seen during cycle peaks in the 20th Century.

No le crean a Pontiac

Jajajajaja, querrás decir no le crean a la NASA y  las entidades eurpoeas, que están advirtiendo en todos los medios hace rato  e incluso Obama hizo unas advertencias, hace poco tiempo.

Esto lo sabe medio mundo en todo caso...   
Que la máxima actividad esta prevista para el 2013 y se habla de seis erupciones solares grandes...

Etc.etc.etc...

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 352 Issued at 2200Z on 17 Dec 2012


IA.  Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
17/0220Z from Region 1629 (N13W88). There are currently 5 numbered
sunspot regions on the disk.

IB.  Solar Activity Forecast: Solar activity is expected to be at low
levels with a slight chance for M-class flares on days one, two, and
three (18 Dec, 19 Dec, 20 Dec).


IIA.  Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
532 km/s at 17/1237Z. Total IMF reached 9.6 nT at 17/0740Z. The maximum
southward component of Bz reached -7.4 nT at 17/1102Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 155 pfu.

IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (18 Dec) and a return to
predominantly quiet levels for days two and three (19 Dec and 20 Dec).
