DOI: 10.1002/2017ja024362
Abstract: We investigate localized thermospheric neutral density increases (or density spikes) developed during the 24 August 2005 geomagnetic storm and utilize a multi-instrument database for monitoring the underlying thermospheric, ionospheric, magnetospheric, and solar wind conditions. We… read more here.

DOI: 10.1016/j.jns.2018.01.029
Abstract: BACKGROUND The Pulfrich phenomenon (PF) is the illusory perception that an object moving linearly along a 2-D plane appears to instead follow an elliptical 3-D trajectory, a consequence of inter-eye asymmetry in the timing of… read more here.

DOI: 10.1029/2019sw002373
Abstract: Space weather is the main source of uncertainty in the position of all objects in low Earth orbit (LEO) below about 1,000 km. The main impact is strong variation in the neutral density of the… read more here.
