NASA's Parker Solar Probe Teams Up With MLSO and WHPI NASA released a story about the The Whole Heliosphere and Planetary Interactions (WHPI) campaign that took place in coordination with Parker Solar Probe’s fourth perihelion. Space Weather Challenge & Forecasting Implications Of Rossby Waves Rossby waves arise in thin layers within fluid regions of stars and planets. These global wave-like patterns occur due to the variation in Coriolis forces with latitude. Boulder scientists’ work key to astonishing images of sun’s surface The highest resolution images of the solar surface ever seen were made possible to no small degree by the work of Boulder based scientists. Global-scale observations and modeling of far-ultraviolet airglow The NASA Global-scale Observations of the Limb and Disk (GOLD) instrument is an ultraviolet imager and spectrograph that observes light from the upper-atmosphere of the Earth, in order to infer qua Front Page Recent News Global Maps of the Magnetic Field in the Solar Corona August 12, 2020 An international team led by solar physicists from Peking University, China and National Center for Atmospheric Research (NCAR), USA, has recently measured the global magnetic field of the solar corona for the first time. HAO affiliate scientist, Dr. Joe Huba, published in a popular-science journal July 23, 2020 Dr. Joe Huba is a Senior Research Scientist at Syntek Technologies in Virginia and a long-standing Affiliate Scientist at HAO. In a Scientia article, he explores the complex process of vast plasma bubbles forming in the upper atmosphere and quickly ascending into space. More news in our archive >> Publication Highlights Comparison of GOLD nighttime measurements with total electron content: preliminary results August 28, 2020 The National Aeronautics and Space Administration (NASA) Global‐scale Observations of the Limb and Disk (GOLD) has been imaging the thermosphere and ionosphere since October 2018. It provides continuous measurements over a large area from its geostationary orbit. Mapping the magnetic field in the solar corona through magnetoseismology August 14, 2020 Magnetoseismology, a technique of magnetic field diagnostics based on observations of magnetohydrodynamic (MHD) waves, has been widely used to estimate the field strengths of oscillating structures in the solar corona. Dynamics of Late-Stage Reconnection in the 2017 September 10 Solar Flare August 4, 2020 In this multi-instrument paper, we search for evidence of sustained magnetic reconnection far beyond the impulsive phase of the X8.2-class solar flare on 2017 September 10.

GET CoMP DATA K-Cor White Light Corona Designed to study the formation and dynamics of coronal mass ejections and the evolution of the density structure of the low corona, K-Cor records the polarization brightness (pB). GET K-COR DATA K-Cor (radially graded filter) K-Cor image with a normalized radially graded filter (nrgf) to maximize image contrast, especially in the outer field. These data are ideal for measuring positions of coronal structures such as CMEs and helmet streamers.
