HAO's anniversary, which will feature a series of public events, celebrates the emergence of Boulder as a hub of solar science.
Seasons on the Sun: Coronal mass ejection in 2012
April 07, 2015
The Sun's activity waxes and wanes nearly every two years. The discovery provides clues that could help improve forecasting of solar storms, which can affect technological systems that society depends on.

A range of observing and modeling tools is helping researchers at NCAR and elsewhere discern previously unmapped links between weather events in various layers of the atmosphere, with implications for aviation, GPS, and other technology society relies on.
Depiction of model-produced meridional circulation beneath solar surface
August 05, 2014
A leading goal of solar scientists is to improve predictions of the Sun's approximately 11-year cycle. New research led by scientists from NCAR and Sweden shows how solar predictions can borrow from weather forecasting techniques in order to predict the timing and extent of the solar cycle.
Space junk: Artist's depiction of space debris circling Earth
July 02, 2014
Space debris poses serious risks to a wide array of satellites critical to society. NCAR is part of a collaborative effort to help reduce those risks by modeling the effects of space weather on satellite orbits, helping operators steer spacecraft more accurately around debris.
Predicting solar superstorms: image of coronal mass ejection on August 31, 2012

While the current peak in the 11-year cycle of sunspot activity is on the weak side, the Sun might still produce a major storm at any point. The most dangerous storms are most likely during the waning part of the solar cycle, which will unfold later this decade.

A grand solar minimum would slow global warming but not stop it.
October 16, 2012
New observations of the magnetic field on the Sun are providing an unprecedented glimpse into solar eruptions that have serious impacts on Earth.
Two forecasters at the National Weather Service test-drive a graphics system.
May 18, 2012
University students and faculty soon will have the chance to peer at day-to-day weather through the same lens used by National Weather Service meteorologists. A new version of the NWS’s workhorse graphics software will reach campuses through UCAR’s Unidata program.
