Webb7 feb. 2024 · Conventionally, several geomagnetic indices are used to assess the strength of a geomagnetic storm. However, for equatorial regions, the most commonly used indices are (i) the disturbance storm time (Dst) index [ 11 – 13] and (ii) the Kp index which is an integer between 0 and 9 [ 13 – 15 ]. WebbPenetration of the interplanetary electric field (IEF) to the middle- and low-latitude ionosphere has been investigated for nearly four decades. Most previous studies focused on the correlation between the interplanetary and ionospheric electric field perturbations.

WebbHowever, thermospheric heating has a completely opposite effect on the O density in the ionospheric altitude range. Oxygen atoms are strongly confined by gravity, so that a temperature increase during the solar maximum produces an increase in the scale height of O which leads to an order of mag- nitude higher density (than that during the solar … WebbCircle Optics proposes a NASA SBIR Phase II project to build, flight test, and deliver, a 7-channel visible DAA visor system. This system would use Sony IMX530 sensors and provide staring type imaging over a ± 112-degree horizontal FOV, with a ± 15-degree vertical FOV, to support a detection range of ~ 3.8 Nm.
