A search through 2--3 months of data from Ogo 6 has revealed about 10 cases of field-aligned precipitation of >30-keV electrons. Brief descriptions are given of the four most spectacular of these events, in which the ratio between precipitated and trapped fluxes reached about 100 in one case. Preliminary indications are that such events occur mainly in the evening and midnight sectors and at high geomagnetic latitudes (usually at or above the trapping boundary for >30-keV electrons).
