                         during the total solar eclipse of 30 June 1992. The surface path 
                         of the totality crossed the VLF propagation path in the sunrise 
                         transition period causing a phase delay of 6.4 microsec. and an 
                         amplitude change of 1.3 dB. The ionospheric response to the Sun's 
                         obscuration was compared with the phase delays reported for 
                         several solar eclipses that occurred from 1966 to 1979. The 
                         results are mainly discussed in terms of the length of VLF 
                         propagation path affected. Some similarities between a sudden 
                         phase anomaly and a reversed eclipse effect are also raised.",
