Chromospheric Flares

In this topical review I revisit the “chromospheric flare”. This should currently be an outdated concept, because modern data seem to rule out the possiblity of a major flare happening independently in the chromosphere alone, but the chromosphere still plays a major observational role in many ways. It is the source of the bulk of a flare’s radiant energy – in particular the visible/UV continuum...

Chromospheric Oscillations

We show results from NSO/Sacramento Peak data to discuss three issues: (i)—the spatial occurrence of chromospheric 3–min oscillations; (ii)—the validity of Ca II H&K line-center Doppler Shift measurements; (iii)—the significance of oscillation power and phase at frequencies above 10 mHz.

Chromospheric Fine Structure Didactically

The solar chromosphere is occupied with a wealth of fine structures referred to by diverse nomenclature. Recent identification of slow-mode magnetoacoustic shocks, excited by p-modes of photospheric oscillations, as plausible drivers of dynamic fibrils and spicules was followed by a surge of observational studies and numerical simulations attempting to reveal the role of chromospheric fine stru...

WP 11 ENGLISH ONLY UNITED NATIONS STATISTICAL COMMISSION and ECONOMIC COMMISSION FOR EUROPE CONFERENCE OF EUROPEAN STATISTICIANS

This paper discusses the role of reporting enterprises in data editing. The approach followed is that of TQM. Hence, suppliers and customers are part of the productive system and a global strategy is needed for an efficient data editing. Some prerequisites to get high quality incoming data are discussed. The paper presents two aspects where reporting enterprises may play an active role in data ...
