Streamer

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
streamer
1. a stream of light, esp one appearing in some forms of the aurora
2. Computing another word for tape streamer

streamer [′strē·mər]
(geophysics)
A sinuous channel of very high ion-density which propagates itself through a gas by continual establishment of an electron avalanche just ahead of its advancing tip; in lightning discharges, the stepped leader, and return streamer all constitute special types of streamers.

Streamer 

a narrow, luminous channel formed within a gas in an electric field at pressures that are close to and above atmospheric in the stage preceding the electrical breakdown of the gas. Upon formation, a streamer lengthens at great velocity (~106 m/sec), a velocity several times higher than that of the charged particles between the electrodes. This speed is explained by the photo-ionization that occurs in the strong electric field created by the space charge near the advancing tip of the streamer. In their structure, streamers are similar in many respects to leaders in lightning discharges.

The night was warm and I was thirsty, and I went stretching my legs clumsily and feeling my way in the dark- ness, to the little table where the siphon stood, while Ogilvy exclaimed at the streamer of gas that came out towards us.
But the Milky Way, it seemed to me, was still the same tattered streamer of star-dust as of yore.
The next morn broke off the coast of Aleria; all day they coasted, and in the evening saw fires lighted on land; the position of these was no doubt a signal for landing, for a ship's lantern was hung up at the mast-head instead of the streamer, and they came to within a gunshot of the shore.
