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.

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).
