Two images of the solar corona in polarized light on August 21, 2017. At left is an image taken during eclipse totality using a PolarCam camera (4D Technology). At right is an image in the same type of polarized light from the Mauna Loa Solar Observatory (MLSO) K-Cor coronagraph camera. Polarized light provides information on the density and magnetic field of the Sun's corona. The K-Cor instrument creates artificial eclipse images of the corona for daily observations of the corona.

For over a decade, Joan Burkepile has participated in the STEM conference for middle school girls called “Expanding Your Horizons,” at CU Boulder. These one-day hands-on workshops are led by women professionals and are designed to be fun and exploratory.
The Sun’s outer atmosphere is heated to temperatures of millions of degrees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our current understanding of these interrelated problems: coronal heating and the acceleration of the ambient solar wind.
We aim to investigate the nature and occurrence characteristics of grand solar minimum and maximum periods, which are observed in the solar proxy records such as 10Be and 14C, using a fully non-linear Babcock-Leighton type flux transport dynamo including momentum and entropy equations.
Formation of Sunspots and Active regions, and Origin of Their Asymmetries—We present a realistic numerical model of sunspot and active region formation based on the emergence of flux bundles generated in a solar convective dynamo.
