The McIntosh Archive of synoptic maps is complete!

In 1964, Patrick McIntosh, a scientist at NOAA’s Space Environment Center in Boulder, CO, began creating hand-drawn synoptic maps of solar magnetic features.

Partnership Continues with NASA's PSP and MLSO–WHPI

Beginning in January 2021, there are new plans underway for continued coordinated efforts between NASA's PSP seventh perihelion and the WHPI campaign.

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 lead 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

CoMP Coronal Intensity

The COronal Multi-channel Polarimeter (CoMP) observes the Fe-XIII emission line at 1074.7 nm to measure the coronal magnetic field and obtain plasma density and motion in the low corona from ~1.03 to 1.5 solar radii.
