Statistical comparison of transition region blinkers and explosive events
Explosive events and blinkers are two observational classes of transients seen on the quiet Sun and an investigation of the significance of and relationship between such events may be critical for understanding basic processes at work in the solar atmosphere. We analysed five time-series spectra of the quiet Sun of transition region O V 629 Å, O VI 1032 Å and O VI 1038 Å lines. We investigated ...
متن کاملIndividual Differences in the Attentional Blink: The Temporal Profile of Blinkers and Non-Blinkers
BACKGROUND When two targets are presented in close temporal succession, the majority of people frequently fail to report the second target. This phenomenon, known as the 'attentional blink' (AB), has been a major topic in attention research for the past twenty years because it is informative about the rate at which stimuli can be encoded into consciously accessible representations. An aspect of...
متن کاملHindsight blinkers Britain's mad cow disease response
Like the Phillips report itself (see box below) into Britain’s handling of the outbreak of bovine spongiform encephalopathy (BSE), the so-called mad cow disease, the newspaper stories accompanying its launch were inevitably written with hindsight. But while the report acknowledged the risks this entailed, press coverage was less scrupulous. Much of it also failed to reflect the scientific uncer...
متن کاملThe transition region above sunspots
Over decades, sunspots and their fine structures have been studied in detail at the photospheric level with different ground-based telescopes, as the surface of the Sun primarily emits light in the visible wavelengths. For a very long period, the upper atmosphere above the sunspot regions, especially the transition region (TR) above sunspots where the plasma emits light in the far ultraviolet (...
متن کاملTransition region and coronal structuring
In this paper we examine regions of internetwork, network and bright network emission, observed in the quiet Sun with the Coronal Diagnostic Spectrometer (cds) onboard SoHO. The slopes of the emission measure distributions, between 5.4 ≤ log Te ≤ 6.0, are found to differ in each region, suggesting the presence of different atmospheric structures. From an analysis of emission area the network is...
