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.
Impacts of atmospheric waves: Photo of EISCAT Svalbard incoherent scatter radar

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

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.
