Abstract
The HST/FOS recorded a remarkable transient brightening in the C IV la mbda lambda 1548,50 emissions of the rapidly rotating Pleiades G dwarf H II 314. On the one hand the ''flare'' might be a rare event luckily observed; on the other hand it might be a bellwether of the coronal h eating in very young solar-mass stars. If the latter, flaring provides a natural spin-down mechanism through associated sporadic magnetosphe ric mass loss.
