COR1 image processed using the Normalizing-Radial-Graded Filter (NRGF)
COR1 image processed using the Normalizing-Radial-Graded Filter (NRGF) technique as described in Morgan, Habbal, and Woo, "The Depiction of Coronal Structure in White-Light Images", Solar Physics, 236, 263-272, 2006. This technique enhances the contrast of coronagraph images, and makes it easier to see the fainter structures far out from the Sun.
Prominence eruption
An erupting prominence glows brightly in this COR1-Ahead image from April 9, 2008. This is by far the brightest prominence seen by COR1 since the start of the mission. Complex twisting motions are seen as the prominence erupts.
Engineers expect contact to be lost with Ulysses very soon
The solar wind - the stream of charged particles billowing away from the Sun - is at its weakest for 50 years.
Scientists made the assessment after studying 18 years of data from the Ulysses satellite which has sampled the space environment all around our star.
They expect the reduced output to have effects right across the Solar System.
Indeed, one impact is to diminish slightly the influence the Sun has over its local environment which extends billions of kilometres into space.
Even though the end is now in sight, every day's worth of new data is adding to our knowledge of the Sun and its environment
Richard Marsden
Esa's Ulysses project scientist
Confirmation of that prediction should come from the far-distant Voyager spacecraft which were launched in the 1970s and are now bearing down on the edge of the heliosphere - the great "bubble" of wind material that surrounds the Sun.
Scientists now predict the Voyagers will hit the edge and cross over into interstellar space - that region considered to be "between the stars" - sooner than anticipated.
Space age
The solar wind, which originates in the Sun's hot outer atmosphere known as the corona, gusts and calms with the star's familiar 11-year cycle of activity (but also over its less well known longer cycles, too).
Calmer wind conditions would be expected to prevail right now, but the Ulysses data indicates circumstances unprecedented in recent times.
The Sun is a variable star; activity rises and falls in cycles
"This is a whole Sun phenomenon," said Dave McComas, Ulysses solar wind instrument principal investigator, from Southwest Research Institute, San Antonio, US.
"The entire Sun is blowing significantly less hard - about 20-25% less hard - than it was during the last solar minimum 10-15 years ago.
"That's a very significant change. In fact, the solar wind we're seeing now is blowing the least hard we've see it for a prolonged time, since the start of those observations in the 1960s at the start of the space age."
In addition to being calmer, the wind measured at Ulysses is 13% cooler.
However, judging from Sun activity data collected by non-satellite methods over the past 200 years, the current behaviour is thought to be well within the long-term norm.
Nonetheless, scientists expect the weakened wind to have a wide range of impacts.
Energetic rays
The charged wind particles also carry with them the Sun's magnetic field, and this has a protective role in limiting the number of high-energy cosmic rays that can enter the Solar System.
More of them will probably now make their way through.
Many of these rays, which include electrons and atomic nuclei, originate in exploding stars and at black holes, and move at colossal speeds.
The Voyager spacecraft will move beyond the solar wind's influence
They pose no major risk to people on Earth because our atmosphere also works to reduce their intensity; but they are a consideration for space operations.
The rays can damage satellite electronics, and if current solar wind conditions persist, engineers would have to take this into account when deciding how to "harden" their spacecraft. Astronauts, too, are at risk from the higher doses of radiation associated with cosmic rays.
"The Sun also puts out cosmic rays in the form of bursts and these bursts are much less frequent at solar minimum. However, when they do occur at solar minimum, they are more lethal, so this is not a good time to be travelling in space owing to both kinds of cosmic rays," explained Professor Nancy Crooker, from Boston University, Massachusetts, US.
"Reduced solar activity also leads to the cooling of Earth's upper atmosphere and if Earth's upper atmosphere is cooler then there is less drag up there on satellites and this means we are left with much more debris up there - which is also something astronauts have to look out for."
Some researchers have attempted to link the intensity of cosmic rays at Earth to cloudiness and climate change. Current conditions may be a good opportunity to test these ideas further.

MYTH Carbon Dioxide levels in our atmosphere at the moment are unprecedented (high).
FACT Atmospheric carbon dioxide levels, currently only 350 parts per million have been over 18 times higher in the past at a time when cars, factories and power stations did not exist — levels rise and fall without mankind's help.
MYTH Mankind is pumping out carbon dioxide at a prodigious rate.
FACT 96.5% of all carbon dioxide emissions are from natural sources, mankind is responsible for only 3.5%, with 0.6% coming from fuel to move vehicles, and about 1% from fuel to heat buildings. Yet vehicle fuel (petrol) is taxed at 300% while fuel to heat buildings is taxed at 5% even though buildings emit nearly twice as much carbon dioxide!
MYTH The recent wet weather and flooding was caused by mankind through 'global warming'
FACT Extreme weather correlates with the cycle of solar activity, not carbon dioxide emissions or political elections, the recent heavy rainfall in winter and spring is a perfect example of this — it occurred at solar maximum at a time when solar maxima are very intense — this pattern may well repeat every 11 years until about 2045.
MYTH There are only a tiny handful of maverick scientists who dispute that man-made global warming theory is true.
FACT There are nearly 18,000 signatures from scientists worldwide on a petition called The Oregon Petition which says that there is no evidence for man-made global warming theory nor for any impact from mankind's activities on climate.
Many scientists believe that the Kyoto agreement is a total waste of time and one of the biggest political scams ever perpetrated on the public ... as H L Mencken said "the fundamental aim of practical politics is to keep the populace alarmed, and hence clamorous to be led to safety, by menacing it with an endless series of hobgoblins, all of them imaginary" ... the desire to save the world usually fronts a desire to rule it.
BUT WHEN YOU SEE THE SCIENCE — HEY THE MYTHS ARE DEAD
THOSE GREEN MYTHS ... GET THEM OUTTA YOUR HEAD
