Ionospheric effects of magnetospheric and thermospheric disturbances on March 17--19, 2015

Using vertical and oblique radio-sounding data, we analyze the ionospheric and thermospheric disturbances during the magnetic storm that occurred in northeastern Russia on March 17\textendash19, 2015. We consider the heliospheric sources that induced the magnetic storm. During the main and early recovery phases, the midlatitude stations are characterized by extremely low values of electron density at the F2 layer maximum. Using oblique sounding data, we recorded signals that propagated outside the great circle arc. In evening and night hours, no radio signals were found to pass along the Norilsk\textendashIrkutsk and Magadan\textendashIrkutsk paths. The observed ionospheric effects are shown to be caused by a sharp shift of the boundaries of the main ionospheric trough to the invariant latitude 46\textdegree N during the main phase of the magnetic storm. The negative ionospheric disturbance during the recovery phase of the storm, which was associated with significant variations in the composition of the neutral atmosphere, led to a change in the mode composition of received radio signals and a decline in observed maximal frequencies in daytime hours of March 18, 2015 by more than 2 times.

Ionospheric effects of solar flares and their associated particle ejections in March 2012

Flares of March 4\textendash9, 2012 were accompanied by an intensification of solar electromagnetic and corpuscular radiations and five coronal mass ejections. Bursts of X-rays and increased solar cosmic ray fluxes caused an increase in ionospheric absorption manifesting itself in data from vertical sounding stations as enhancements of the lowest frequency of reflections up to 4\textendash6\ MHz at the daytime and as the disappearance of reflections in the ionograms of high latitude stations. Interplanetary coronal mass ejections (ICME) generated March 7\textendash8 moderate and March 8\textendash11 intense magnetic storms accompanied by ionospheric disturbances. At the peaks of both magnetic storms there were abrupt afternoon\textendashevening decreases in the ionospheric F2-layer critical frequency (foF2). During the March 7\textendash8 storm, the foF2 decrease concurred with the reversal of the interplanetary magnetic field azimuthal component (IMF By) which initiated restructuring of magnetospheric convection; during the March 8\textendash11 storm, with the abrupt weakening of the interplanetary magnetic field southward component (IMF Bz) which triggered a substorm.

Near Earth space plasma monitoring under COST 296

This review paper presents the main achievements of the near Earth space plasma monitoring under COST 296

Action. The outputs of the COST 296 community making data, historical and real-time, standardized and available\ to the ionospheric community for their research, applications and modeling purposes are presented. The contribution\ of COST 296 with the added value of the validated data made possible a trusted ionospheric monitoring\ for research and modeling purposes, and it served for testing and improving the algorithms producing real-time

data and providing data users measurement uncertainties. These value added data also served for calibration and

validation of space-borne sensors. New techniques and parameters have been developed for monitoring the near\ Earth space plasma, as time dependent 2D maps of vertical total electron content (vTEC), other key ionospheric\ parameters and activity indices for distinguishing disturbed ionospheric conditions, as well as a technique for improving\ the discrepancies of different mapping services. The dissemination of the above products has been developed\ by COST 296 participants throughout the websites making them available on-line for real-time applications.
