Analysis of the radiation of coronal suprathermal streams

This paper reports on the first measurements of the color index of the coronal suprathermal streams. Observations performed during the total eclipse of 2001 in Angola imply that the color index of streams differs markedly from that for adjacent parts of the surrounding corona taken as reference. The registered drifts to the longwave and shortwave domains of the spectrum are in agreement with theoretical results obtained recently by the authors.Published in Astrofizika, Vol. 48, No. 1, pp. 79–85 (February 2005).
