英文摘要This short paper presents the statistics of spread-F occurrence at four low-mid latitude locations (17.0 degrees N, 21.2 degrees N, 26.5 degrees N and 36.5 degrees N mag. lat.) in Japan longitude sector (similar to 135 degrees E) in March to April 2002, 2003 and 2006 ( high, medium and low solar activity). The location of a spread-F minimum predicted by theoretical models is identified for the first time. The spread-F minimum occurs at the poleward side of the equatorial ionisation anomaly crest and shifts equatorward from similar to 25 degrees N mag. lat. at high solar activity to below 17 degrees N at low solar activity. The corresponding spread-F maximum occurring on the poleward side of the minimum also shifts equatorward from similar to 35 degrees N (or beyond) at medium solar activity to 20 degrees-25 degrees N at low solar activity. The spread-F occurrence increases with decreasing solar activity at all locations especially at higher latitudes (> similar to 25 degrees N) where there is almost no occurrence at high solar activity.
