Space Weather Swings Between Extreme Effects Roughly every 11 years, headlines announce the peak of a natural variation known as the solar cycle, pointing to a proliferation of sunspots, potentially dangerous solar flares and beautiful aurora. This period of increased activity is known as solar maximum, the latest of which is predicted to arrive in August. But scientists who study the sun say that we should be paying just as much attention to the sun’s calmer periods. “Space weather doesn’t go away during solar minimum, it just changes form and approaches a different extreme,” said astrophysicist Madhulika Guhathakurta, who lead’s NASA’s “Living With a Star” project and co-authored an opinion piece on this topic that appeared in Space Weather March 19. The solar cycle, say scientists like Guhthakurta, is an oscillation between two extreme states, each with their own distinct conditions and hazards, rather than a simple change between periods of high and low activity.
Today's Space Weather The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. Click on a data panel to open an updating secondary window. An updating Satellite Environment Plot window is also available. Although these data are of interest to the satellite community, they do not include all parameters and energy ranges known to be associated with satellite anomalies.

Life's Little Mysteries For millennia, people have looked up to the sky and wondered about celestial bodies. The sparkling stars and fiery sun hold mystery and wonder. To astronomers, the sun is just another dying star, but to everyone else it’s a huge burning ball that gives heat, light, and life. So far so good. But what is it burning? We all know that there is no air in space, and therefore no oxygen to burn. The Sun l Sun Facts and images. Our Sun is a normal main-sequence G2 star, one of more than 100 billion stars in our galaxy. diameter: 1,390,000 km. mass: 1.989e30 kgtemperature: 5800 K (surface) 15,600,000 K (core) History of The Sun The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System (Jupiter contains most of the rest). It is often said that the Sun is an "ordinary" star.

Solar observatory A solar observatory is an observatory that specializes in monitoring the Sun. As such, they usually have one or more solar telescopes. The Einstein Tower was a solar observatory in the Albert Einstein Science Park in Potsdam, Germany. Solar observatories study phenomena associated with the Sun. The Sun, being the closest star to earth, allows a unique chance to study stellar physics with high-resolution. Sept-Îles Clear Sky Chart It's the astronomer's forecast. At a glance, it shows when it will be cloudy or clear for up to the next two days. It's a prediction of when Sept-Îles, QC, will have good weather for astronomical observing. The data comes from a forecast model developed by Allan Rahill of the Canadian Meteorological Center. CMC's numerical weather forecasts are unique because they are specifically designed for astronomers.

MessageToEagle.com - UPDATE: This article has now been updated with additional information from NASA including images and video! The Sun's odd behavior has been mentioned on many occasions recently. As we all await the Solar Cycle 24, scientists keep a close eye on the Sun. Now astronomers have discovered huge dark strip on the surface of the Sun. It is estimated this filament is about 800,000 km in length! Astrophysicists presume dark spots on the Sun are areas where the temperature is lower.
