  • Abstract
    The temporal variations of the low-latitude spread-F (SF) observed by DPS-4D digisonde at Nicosia during low solar activity from January 2009 to December 2010 are studied. The spread F measured by the digisonde were classified into two types, i.e., mixed SF (MSF) and range SF (RSF). The statistical results show that the MSF and RSF are outstanding irregularities in Cyprus which occur in all three seasons (equinox, summer, winter). Both types have a diurnal peak before midnight and usually appear during 20:00-06:00 UT.
