Abstract: We analysed geomagnetic field variations in 1 1000 s period range that accompanied 33 rocket launches in 2002–2007. The measurements were made near Kharkiv city at a distance of about 5000м6000 km from the China cosmodromes. Our analysis revealed three groups of disturbances with time delays of 39–53, 100–129 and 140–180 min and with durations of 30–50, 37–45 and 38–57 min, respectively. The 9–12 min geomagnetic micropulsation periods became dominant, and their amplitudes attained a value of 3–5 nT.
