Abstract: Hour-to-hour and day-to-day variations at Udaipur (24°35'N) of ionospheric absorption during moderate and high solar activity periods (1978-80) are presented. The occurrence of two maxima in the diurnal variation of absorption due to solar flare, due to nearness of the working frequency to the critical frequency of the reflecting region and in the presence of sporadic- E (blanketing or flat type) is discussed. The day-to-day variations of absorption in the light of day-to-day variations of 10.7-cm solar flux, sunspot number and 1-8 Å X-ray flux have also been discussed.
