Документ Travelling ionospheric disturbances over Kharkiv, Ukraine, accompanying the operation of EISCAT heater facility(НТУ "ХПІ", 2014) Panasenko, S. V.; Rietveld, M. T.; La Hoz, C.; Domnin, I. F.We have detected the travelling ionospheric disturbances (TIDs) over Kharkiv with periods of 40–80 min occurring in the time range between 09:00 and 10:30 UT on November 22 and between 10:00 and 12:00 UT on November 23, 2012 during and after the operation of the EISCAT heater facility. The duration of these disturbances were less than 120–180 min. The relative amplitudes of the TIDs in electron density ranged from 0.05 to 0.15 and those in electron and ion temperatures were about 0.02 – 0.05. Assuming that these TIDs have been generated in the heated region, we described the possible mechanisms of their generation.Документ Variations of the electric field zonal component, the vertical component of the plasma drift and neutral wind velocities in ionosphere over Kharkov (Ukraine) during August 5–6, 2011 and November 13–15, 2012 magnetic storms(НТУ "ХПІ", 2014) Domnin, I. F.; La Hoz, C.; Lyashenko, M. V.The modeling results of the zonal electric field and the vertical component of the plasma transfer velocity due to electromagnetic drift during August 5–6, 2011 and November 13 – 15, 2012 magnetic storms were presented. Confirmed that has a penetration of electric fields from magnetospheric origin in the mid-latitude ionosphere during strong geomagnetic disturbances. For the considered disturbed periods the neutral wind parameters were calculated using Kharkov incoherent scatter radar data.
