No. 52: Jul-Aug 1987
July 21, 1985. Strait of Malacca. m.v. Staffordshire.
"Between 2000 GMT and 2200 GMT whilst the vessel was transiting the Strait of Malacca in a southeasterly direction, the following phenomenon was observed.
"For several hours lightning had been seen ahead of the vessel. As we approached, it appeared to take on several forms, the most interesting of which is shown in the sketch. It had the appearance of a central point of light with ragged streaks radiating from the centre in a mainly horizontal direction. At no time did this lightning reach the sea surface. This type was observed about ten times during the period of observation..."
