(Active Magnetospheric Particle Tracer Explorer–UK Satellite) observations, however, which reveal a dramatic new complex structure within the solar wind flow. In the plasma and field observations of this magnetic hole/current sheet system, the layers surrounding the strong rotation in the magnetic field contain compressed and heated solar wind, an enhanced field strength and considerable wave activity. The interior region shows strong ion heating but with ambient densities and a fluctuating magnetic field which dips to low values. The bulk flow velocity inside is deflected sharply from the anti-sunward direction, but not in the direction predicted by magnetic stresses across the boundary. The structure is expanding in thickness and is relatively young. The source of momentum and energy for this event remains unclear, and could even be magnetospheric.</description><identifier>ISSN: 0028-0836</identifier><identifier>EISSN: 1476-4687</identifier><identifier>DOI: 10.1038/318269a0</identifier><identifier>CODEN: NATUAS</identifier><language>eng</language><publisher>London: Nature Publishing Group UK</publisher><subject>Astronomy ; Earth, ocean, space ; Exact sciences and technology ; Humanities and Social Sciences ; Interplanetary space ; letter ; multidisciplinary ; Science ; Science (multidisciplinary) ; Solar system</subject><ispartof>Nature (London), 1985-11, Vol.318 (6043), p.269-271</ispartof><rights>Springer Nature Limited 1985</rights><rights>1986 INIST-CNRS</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c373t-3bbb2f6f6f95960285d560ec3dbdc8b73067d2c8baba6f08ea0436b28413bc4c3</citedby><cites>FETCH-LOGICAL-c373t-3bbb2f6f6f95960285d560ec3dbdc8b73067d2c8baba6f08ea0436b28413bc4c3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,2727,27924,27925</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=8528395$$DView record in Pascal Francis$$Hfree_for_read</backlink></links><search><creatorcontrib>Schwartz, Steven J</creatorcontrib><creatorcontrib>Chaloner, Chris P</creatorcontrib><creatorcontrib>Christiansen, Peter J</creatorcontrib><creatorcontrib>Coates, Andrew J</creatorcontrib><creatorcontrib>Hall, David S</creatorcontrib><creatorcontrib>Johnstone, Alan D</creatorcontrib><creatorcontrib>Gough, M.
