At the beginning of the event the radio sources are located on a rather small volume in the vicinity of the flare site. In a timescale of only a few minutes the radio emission sites spread over a large volume in the corona, covering a range of 100\u00b0 in heliolatitude. During the period of the radio event the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SOHO) observed an extremely fast coronal mass ejection (CME), with a velocity around 2000 km s<jats:sup>\u22121<\/jats:sup>. This CME presents the particularity of having a fast lateral expansion, giving it a shape reminiscent of a \u201ccoat hanger.\u201d There is a very good association between the latitudinal extent and time development of the CME seen by LASCO and the radio sources recorded by the radio instruments.<\/jats:p>","DOI":"10.1029\/1999ja900033","type":"journal-article","created":{"date-parts":[[2002,9,17]],"date-time":"2002-09-17T22:30:28Z","timestamp":1032301828000},"page":"12507-12513","source":"Crossref","is-referenced-by-count":63,"title":["Radio signatures of a fast coronal mass ejection development on November 6, 1997"],"prefix":"10.1029","volume":"104","author":[{"given":"D.","family":"Maia","sequence":"first","affiliation":[]},{"given":"A.","family":"Vourlidas","sequence":"additional","affiliation":[]},{"given":"M.","family":"Pick","sequence":"additional","affiliation":[]},{"given":"R.","family":"Howard","sequence":"additional","affiliation":[]},{"given":"R.","family":"Schwenn","sequence":"additional","affiliation":[]},{"given":"A.","family":"Magalh\u00e3es","sequence":"additional","affiliation":[]}],"member":"13","published-online":{"date-parts":[[1999,6]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1029\/94GL01577"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00733434"},{"key":"e_1_2_1_4_1","first-page":"499","article-title":"Joint Ulysses and Wind observations of a particle event in April 1995","volume":"316","author":"Buttighoffer A.","year":"1996","journal-title":"Astron.
