Ionosonde observations of ionospheric disturbances due to the 15 February 2013 Chelyabinsk meteor explosion.==$Journal of Geophysical Research: Space Physics, 120$==(11), 9988-9997. https://doi.org/10.1002/2015JA021767http://hdl.handle.net/20.500.12816/3708We report the results of our investigations on the potential ionospheric effects caused by the 15 February 2013 Chelyabinsk meteor explosion. We used the data from a number of digisonde stations located in Europe and Russia to detect the traveling ionospheric disturbances (TIDs) likely to have been caused by the meteor explosion. We found that certain characteristic signatures of the TIDs can be identified in individual ionogram records, mostly in the form of Y‐forking/splitting of the ionogram traces. Based on the arrival times of the disturbances, we have inferred the overall propagation speed of the TIDs from Chelyabinsk to be 171 ± 14 m/s.application/pdfenginfo:eu-repo/semantics/restrictedAccessTraveling ionospheric disturbancesGravity wavesIonosonde measurementsinfo:eu-repo/semantics/articlehttp://purl.org/pe-repo/ocde/ford#1.05.01Journal of Geophysical Research: Space Physicshttps://doi.org/10.1002/2015JA021767
