Two-dimensional spectral observations of sunspots in chromospheric lines
We present two-dimensional spectral observations of two closely located small sunspots in chromospheric lines. Line asymmetries and shifts are derived for the Ca ii K line in particular. It is found that the majority of Ca ii K profiles show a blue asymmetry. Red asymmetry may also appear, but only in some tiny regions. Some ephemeral blue asymmetry patches are found in the umbrae, which seem t...
متن کاملChromospheric polarity reversals on sunspots Are they consistent with weak line emission?
Photospheric and chromospheric solar magnetograms sometimes show opposite polarity. This intriguing phenomenon is associated with the emergence of magnetic flux and with nearby, but not necessarily superposed, flaring activity. Despite the fact that there may be different explanations, it is shown here that the observed reversals are consistent with weak flare-like line emission all over the re...
متن کاملChromospheric 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 This should currently be an outdated concept, because modern data seem to rule out the possiblity of a major flare happening independently in the chromosphere alone, but the chromosphere still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...
متن کاملSunspots and Temperatures
Power spectrum analyses of temperature series at New York City (1822-1956), the Netherlands (1735-1944), and central England (1698-1955) show that the only significant energy in these spectrums appears at the annual period of 12 months. No significant energy was found corresponding to any known sunspot periodicity. Correlation coefficients between January and July temperatures for the years of ...
متن کاملSunspots, correlation and competition
Correlated equilibria in strategic market games played, simultaneously, by “overlapping generations” of players correspond to sunspot equilibria in the associated, competitive economy. The lower the degree of competition, the larger the range of parameters that allow for effective correlation or endogenous stochastic fluctuations.
