solar activity

The number of sunspots is usually taken as an indicator of solar activity .

The thermosphere interacts strongly with the sun and hence is greatly influenced by the sun's solar activity, which occurs in cycles.

However, the complex space environment, solar activity frequently, precision orbit determination and a great impact.

The solar activity and volcanic eruptions are the main factors of climatic changes during the Little Ice Age.

NASA will attempt to explain the increasing blackouts and tail debris by claiming solar activity and the proliferation of space junk.

The scaled smoothed sunspot number is shown in red to indicate the phase of the solar activity cycle.

The weakening of solar activity this winter and the Gulf Stream changes have also increased the rate of cooling in Europe.

The increase in solar activity is caused only in part by the Dark Star, multiple factors being at play. These are complex.

Two sunspots are visible on our star's face for the first time in more than a year, possibly ending an unexpected lull in solar activity.

If correct, the years ahead could produce a burst of solar activity second only to the historic Solar Max of 1958.

Enhanced heating of the stratosphere could be behind the heightened effects felt by Europe of changes in solar activity.

The chaotic attractor also shows that it's impossible to predict the long-term solar activity.

"This year we're at the record low minimum for solar activity. The fact we're having record high temperatures is remarkable, " Masters said.

Active regions are in a sense the fundamental unit of solar activity and the most persistent and visible manifestation of solar magnetism.

Intense solar activity causes disruptions of the belts, linked in turn with such phenomena as auroras and magnetic storms.

There is evidence that low solar activity increases their numbers , and the sun is currently in a period of minimum activity.

He points out that the ice remained in Europe long after solar activity picked up from the Maunder minimum.

Intense solar activity may generate inaccuracy in information in these systems, causing errors in the positioning of vehicles.

Thecombined data indicate that we may soon be headed into what's known as a grandminimum, a period of unusually low solar activity.

So in times of heightened solar activity, the stratosphere heats up and this influences the winds in that layer.

Recently UK researchers linked low solar activity and freezing cold winters in Europe.

While solar activity is currently increasing in its standard 11-year cycle, this same cycle has occurred over millennia.

The space age has coincided with a period of unusually high solar activity, called a grand maximum.

The Sun follows an 11-year cycle of high and low periods of solar activity.

The Earth could enter a new 'Little Ice Age' in the coming years due to low solar activity, astronomers believe.

Freak solar activity creates incredible Northern Lights which are seen as far south as Arkansas.

He noted that in 2010, when solar activity was mostly absent, Earth tied for its hottest year in more than a century of record-keeping.

Variation of space environment is driven by solar activity. Space radiation will lead to biological effects of space radiation.

The Theories of various solar dynamos to explain the origin of solar activity are reviewed.

Conversely, when solar activity is less intense, more cosmic rays get through.

Their birth dates were checked against levels of solar activity at the time, and then compared with the diseases they had contracted.

Earlier modelling of a period of prolonged low solar activity in the 17th and 18th centuries showed similar patterns.

Solar activity varies over an 11-year cycle, but it experiences longer-term variations, highs and lows that can last around a century.

That could affect weather on Earth because low solar activity has been linked to low global temperatures in the past.

Solar activity has a regular cycle, with peaks approximately every 11 years.

A: Solar activity has a regular cycle, with peaks approximately every 11 years.

If a change in the jet stream really is a leading indicator of solar activity, then no new cycle is on the horizon.

Solar activity rises and falls on a regular cycle of about 11 years.

What is the link between solar activity and global warming?

Now, as 2012 approaches, Vicino says he is actually more worried about 2013, when solar activity is expected to increase significantly.

The more we know about solar activity, the better we can protect ourselves.
