Bolaji Segun is a visiting researcher to HAO working with Qian Wu using the TIEGCM community model to study equatorial ionosphere variations caused by geomagnetic activities and stratospheric warming. He received his Ph.D from the prestigious University of Ilorin, Nigeria, in 2012 under the supervision of Prof. J.O. Adeniyi, Prof. I.A. Adimula, and Prof. S.M. Radicella (ICTP, Trieste, Italy).

1999 total eclipse
August 23, 2016

On August 21, 2017, Paul Bryans and his team of scientists will be ready to aim a spectrometer at the sun during total eclipse in an effort to detect the effect of magnetism on certain wavelengths of infrared light emitted by the corona. His team includes himself, Phil Judge, Brandon Larson, Scott McIntosh, Scott Sewell–of HAO and James Hannigan, Stephen Shertz–of ACOM.

Downscaling simulation of gravity waves
August 15, 2016

National Center for Atmospheric Research Whole Atmosphere Community Climate Model (WACCM) with ≈0.25 degree horizontal resolution can resolve gravity waves with horizontal scales down to ≈250 km.

We perform the first ever global-scale, altitude-dependent analysis of polar ionospheric conductivity variability using spectrally-resolved in-situ satellite particle measurements.  Our results show that height-integrated conductance and height-dependent conductivities are distinctly different.

Although listed as one of the most significant events of the last 80 years, the space weather storm of late May 1967 has been of mostly fading academic interest.

MLSO Latest Images

H-alpha Disk and Limb

Currently, H-alpha images are obtained by the GONG network, operated by the National Solar Observatory .


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).


K-Cor (radially graded filter)

K-Cor image with filter applied to maximize image contrast, especially in the outer field.
