The first midlatitude F-region VHF radar observations of small-scale field-aligned irregularities (FAI) are described. Looking northward at about 34-deg elevation, the locus of perpendicularity with the geomagnetic field B remains inside the radar beam, such that FAI can be observed, at radar ranges from 350 to over 800 km or F-region altitudes from 200 to 500 km. The preliminary results presented here show the large-scale (greater than 20 km) configuration of small-scale (322.6 cm, half the radar wavelength) F-region irregularities as well as typical spectral results. The most important finding is that, at least on some occasions, there is a quasi-periodic variation in time and space, on scales of approximately 12 min and 50 km, of the observed plasma instabilities.
