TL;DR: The discovery of three previously unreported comets during the initial 2.3 yr of satellite coronal observations suggests that sungrazers are much more common than one might suppose from the list of only nine known comets observed during the years 1668-1970 as mentioned in this paper.

TL;DR: A plausible candidate flare was identified for each of the four major Forbush-like decrease events that were observed in the outer heliosphere in mid-1982 as discussed by the authors, and the identified flare was 35 deg or less in ecliptic longitude from the affected satellite.

TL;DR: In this paper, simultaneous visible-light and radio observations of a coronal transient that occurred on April 9, 1980 are discussed, and it is suggested that an entire coronal arcade rather than just a single loop participated in the event.

TL;DR: The first X-class flare in four years occurred on 9 July 1996 as mentioned in this paper and reached its maximum at 09:11 UT and was located in active region 7978 (S10° W30°) which was an old-cycle sunspot polarity group.

TL;DR: In this article, a rocket-borne coronagraph utilizing external occulting disks was used to photograph the solar corona from 3 to 9 Rs at 1931 UT on 7 March, 1970.
