The paper presents the ionospheric effects due to radiation from the transient extraterrestrial sources like Gamma Ray Bursts, Soft Gamma Ray Repeaters, Anomalous X‐ray Pulsars, X‐ray novae and X‐ray transient sources. Gamma rays could penetrate deep in the atmosphere due to their high energy in comparison with other types of radiation. If the transient radiation from the above sources is strong enough to enhance the ionospheric ionization, VLF radio propagation could be affected. In the paper, we discuss the evidences of detection of such phenomena in VLF data and explain some of the observations using theoretical considerations.
