Abstract
Observations of the quiet-Sun network in the UV emission line Si IV 1393 Å over a time period of two hours are presented. Bursts of explosive events, highly Doppler-shifted emission seem to be sporadically emitted from the brighter regions of the network lanes. Individual events have typical lifetimes of ≈ 1-6 min and come in bursts of up to 30 min, The most spectacular burst in this dataset, shown in the accompanying movie, lasts ≈ 30 min and shows a wide variety of line profiles with both red and blue shifts ≈ 180 km s-1. There appears to be no characteristic form or evolutionary pattern to the line profiles in either the individual events or series of events. There are about twice as many blue shifts as red shifts.
