It is noticed at this station (Poona, lat. 18° 31' N, long. 73° 52' E) that there is a sudden fall in atmospherics activity at midnight on the 27 kc/s band, on a majority of nights during the period January 1958 to April 1960. In fact, out of 546 nights, on 382 nights (70 per cent) there is a fall and only on 86 nights (15.7 per cent) is there a rise; while on 78 nights (14.3 per cent) there is neither a fall nor a rise in the level of activity. The fall in activity is explained on the basis of a sudden decrease in the number of sources of atmospherics round about this hour when the belt of evening peak activity of thunderstorms crosses the west coast of Africa. Also a comparison of the geomagnetic data is found to indicate that during a magnetically undisturbed period a greater fall in activity at midnight occurs. The two effects may act simultaneously to produce the observed effects.
