TL;DR: In this paper, X-ray images of the solar corona showed a magnetically open structure in the low corona which extended from N20W20 to the south pole.
Abstract: X-ray images of the solar corona showed a magnetically open structure in the low corona which extended from N20W20 to the south pole. Analysis of the measured X-ray intensities shows the density scale heights within the structure to be typically a factor of two less than that in the surrounding large scale magnetically closed regions. The structure is identified as a coronal hole. Wind measurements for the appropriate period were traced back to the sun by the method of instantaneous ideal spirals. A striking agreement was found between the Carrington longitude of the solar source of a recurrent high velocity solar wind stream and the position of the hole.

TL;DR: In this article, data from an Aerobee rocket carrying three large-area geiger counters have revealed a considerable flux of radiation in the night sky and the bulk of the radiation is soft x rays from sources outside the solar system.
Abstract: Data from an Aerobee rocket carrying three large-area geiger counters have revealed a considerable flux of radiation in the night sky. Analysis of these data indicates the bulk of the radiation is soft x rays from sources outside the solar system. Synchrotron radiation by cosmic electrons is a possible mechanism for the production of these x rays. Ordinary stellar sources could also contribute a considerable fraction of the observed radiation.

TL;DR: In this article, a new pulsating X-ray source with a 1.24-sec period in the constellation Hercules was discovered, which was interpreted as due to an occulting binary system, with the intensity changes due to occultation of the Xray source by its companion.
Abstract: We have discovered a new pulsating X-ray source with a 1.24-sec period in the constellation Hercules. Analysis of 5 months of data has shown the existence of periodic variations in the intensity of the source and correlated sinusoidal variations in the period of the 1.24-sec pulsations. As in the case of the pulsating X-ray source Cen X-3, we interpret this effect as due to an occulting binary system, with the intensity changes due to occultation of the X-ray source by its companion and with the sinusoidal variations in the period of the 1.24-sec pulsations due to the Doppler effect. In addition, we have observed a longer-time scale cycle in which the source is bright and pulsing for approximately 9 days during which we can observe the 1.7-day occulting, followed by approximately 27 days during which the source is not detected above background on individual 20-sec scans.

TL;DR: In this paper, the association of high-speed solar wind with coronal holes during the Skylab mission was investigated by direct comparison of solar wind and coronal X-ray data; comparison of near-equatorial coronal hole area with maximum solar wind velocity in associated streams; and examination of the correlation between solar and interplanetary magnetic polarities.
Abstract: We investigate the association of high-speed solar wind with coronal holes during the Skylab mission by: (1) direct comparison of solar wind and coronal X-ray data; (2) comparison of near-equatorial coronal hole area with maximum solar wind velocity in the associated streams; and (3) examination of the correlation between solar and interplanetary magnetic polarities. We find that all large near-equatorial coronal holes seen during the Skylab period were associated with high-velocity solar wind streams observed at 1 AU.
