(a) Variations of the H-field minus the quiet day H -field (SqH) at pairs of equatorial and low-latitude stations in Indian (Trivandrum, Alibag), Pacific (Guam, Chichijima) and Peruvian (Huancayo, Fuquene) longitudes on 25 and 26 June, 1998 (UT). (b) The variations of ΔH at Trivandrum and Alibag superimposed at midnight for the period 22 UT on 25 June, 1998, to 10 UT on 26 June, 1998. (c) The difference of ΔH at Trivandrum and Alibag from 22 UT on 25 June, 1998, to 10 UT on 26 June, 1998, (03 h to 15 h local time) from quarter-hourly values.
