Scientists predict sun may `hibernate´

News sources are publishing information regarding new scientific research which
puts our
sunspot cycle into question. How does this affect the average shortwave
listener? Periods of
high sunspot numbers generally produce excellent DX conditions. In other words,
with
modest equipment, listeners can hear even weak signals around the world.
Amateur radio
operators find that they can communicate around the world with very low power.
Our current cycle (cycle 24) has been relatively uneventful compared to the
past-but the
prediction for Cycle 25 is scary. Indeed, it may not even happen on schedule.
The news
sources below explain in detail.
Spaceref.com:
A missing jet stream, fading spots, and slower activity near the poles say
that our Sun is
heading for a rest period even as it is acting up for the first time in years,
according to
scientists at the National Solar Observatory (NSO) and the Air Force Research
Laboratory
(AFRL).
As the current sunspot cycle, Cycle 24, begins to ramp up toward maximum,
independent
studies of the solar interior, visible surface, and the corona indicate that
the next 11-year
solar sunspot cycle, Cycle 25, will be greatly reduced or may not happen at all.
From Yahoo:
For years, scientists have been predicting the Sun would by around 2012
move into solar
maximum, a period of intense flares and sunspot activity, but lately a curious
calm has
suggested quite the opposite.
According to three studies released in the United States on Tuesday,
experts believe the
familiar sunspot cycle may be shutting down and heading toward a pattern of
inactivity
unseen since the 17th century.
Science Mag:
Things may be about to get very dull on the sun. Three different
measurements of solar
activity, reported by scientists at a press conference today, suggest that the
next 11-year-
long solar cycle will be far quieter than the current one. In fact, it may not
happen at all:
Sunspots, the enormous magnetic storms that erupt on the sun´s surface as the
cycle builds,
might disappear entirely for the first time in approximately 400 yearsStandard
