Three features of solar flare effects on 164 kHz radio waves propagated over a distance of about 1600 km from Tashkent to Delhi are identified. These are: (1) sudden enhancement of field strength followed by gradual recovery (type I); (2) sudden decrease of field strength followed by gradual recovery (type II); and (3) sudden decrease, rapid increase and gradual recovery (type III). Type I effects occur mostly during June to October, whereas effects of types II and III occur mostly during November to May. Statistical analysis shows that in a majority of cases relatively large X-ray flux enhancements in the range 0-10 A are necessary for type I and III effects to occur, whereas type II effects could be observed with lesser X-ray enhancements. It appears that differences in solar X-ray spectrum near the time of peak X-ray enhancement are not likely to account for the different types of observed solar flare effects on 164 kHz.
