A High-Temperature Component in Coronal Holes as Confirmed by a Partial-Eclipse Observation
Abstract
We confirmed X-ray signals in coronal holes based upon a Yohkoh soft X-ray observation of a partial eclipse on 1993 November 13. The observed X-ray signals cannot be explained by those coming from one-million-degree plasmas alone, which were observed with the Skylab UV and EUV instruments. This suggests that higher-temperature plasmas are necessary to explain the present observation.
