Shibaji Chakraborty successfully sat his PhD Preliminary Exam on Wednesday, November 13 before a committee of seven professors. Shibaji has authored and co-authored papers that focus on the impacts of solar flares on the ionosphere, in particular, the effects of the ionization enhancement that leads to shortwave fadeout (SWF). This is the fastest form of space weather felt by Earth with only an 8 min delay for propagation of enhanced X-ray and EUV radiation from the sun. Shibaji is currently developing a model that incorporates the physis and chemistry that are needed to account for HF absorption in the ionospheric D region during geomagnetic disturbances. He now passes into PhD Candidate status.

Congratulations, Shibaji!
