Nighttime observations of radio stars were made at four frequencies in the band 22-38 MHz with the 1000 foot reflector at Arecibo, Puerto Rico. Weak ionospheric irregularities were a consistent feature in the 21.00-04.00 LEM.T. period. Observations were made in the fall of 1964 and the spring of 1965 when the sunspot number was low. The maximum scintillation activity took place at 01.00 L.M.T. The time of maximum is the same as that observed for the maximum occurrence of spread-F during low sunspot number years. By measuring scintillation index as a function of wavelength, it was determined that the irregularity height was close to 300 km. In a related study during this time period, satellite scintillations at 40 MHz were observed. It was shown that the weak ionospheric irregularities at night are uniform over a large range of latitudes. Scintillation indices increase rapidly at sub-auroral and auroral latitudes such as Sagamore Hill, Massachusetts and Thule, Greenland.
