Description:
We present results of the new observations of artificial periodic irregularities (APIs) in the ionosphere using the HAARP heating facility carried out in late May and early June, 2014.The objective of this work is to detect API using high-latitude facility, and analyze possible differences of the temporal and spatial variations of the API echoes in the high (HAARP) and mid (SURA) latitudes. Irregularities were created by the powerful wave of X-mode and were sounded using the short probing pulses signals of X-mode. API echoes were observed in the D-, E- and F-regions of the ionosphere. Amplitudes and characteristic times of the API echoes were measured. The API growth and decay times at HAARP (high latitudes) observed were similar to those at the SURA heating facility (mid latitudes).
