Mausumi Dikpati of HAO has won a 2017 Wenner-Gren guest professorship award of Stockholm. This prestigious award is given annually to 6–8 scientists worldwide from all areas of science. About 30–50 scientists get nominated each year.

Stan Solomon wins UCAR 2016 Mentoring Award
December 9, 2016

HAO won three of four outstanding accomplishment awards at the UCAR staff annual holiday celebration and awards presentation. UCAR President Antonio Busalacchi announced the winners to be Stan Solomon for “Mentoring”, and Mark Miesch for “Education and Outreach.” HAO also received the “Scientific and/or Technical Advancement” award for the TIE-GCM model.

Learning about Magnetism
November 11, 2016

On November 5, 2016 UCAR/NCAR held its annual Super Science Saturday event at the Mesa Lab in Boulder. Kids of all ages were treated to a variety of interactive exhibits including hands-on activities, Science Wizard shows and demonstrations that illustrated fundamental scientific discovery in a fun and engaging environment.

Time evolution of two bipolar magnetic regions (BMRs)
January 9, 2017

We develop a three-dimensional kinematic self-sustaining model of the solar dynamo in which the poloidal field generation is from tilted bipolar sunspot pairs placed on the solar surface above regions of strong toroidal field by using the SpotMaker algorithm and then the transport of this poloida

Response functions to a horizontal 1 G magnetic field of the emergent Q linear scattering polarization
January 9, 2017

The linearly polarized solar limb spectrum caused by the absorption and scattering of anisotropic radiation has a very rich diagnostic potential, given its sensitivity to the thermal, dynamic and magnetic structure of the solar atmosphere.

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.

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).
