A1 absorption data on four operating frequencies, 1.8, 2.0, 2.2 and 2.5 MHz over a period of two years (1972-74) at Trivandrum (dip 0.6 deg S, geograph. lat. 8.6 deg N, long. 76.9 deg E) has been analyzed to study its diurnal, long term, and frequency variations. An empirical relation has been established between noon absorption and solar X-ray and 10.7 cm fluxes. Using this relation, the seasonal cos chi index has been evaluated. The deviation of the estimated absorption using this empirical relation from the observed absorption is found to be less than 10%.
