متن کاملPredicting the occurrence of super-storms
A comparative study of five super-storms (Dst<−300 nT) of the current solar cycle after the launch of SoHO, to identify solar and interplanetary variables that influence the magnitude of resulting geomagnetic storms, is described. Amongst solar variables, the initial speed of a CME is considered the most reliable predictor of the strength of the associated geomagnetic storm because fast mass ej...
متن کاملAre investors moonstruck? Lunar phases and stock returns
This paper investigates the relation between lunar phases and stock market returns of 48 countries. The findings indicate that stock returns are lower on the days around a full moon than on the days around a new moon. The magnitude of the return difference is 3% to 5% per annum based on analyses of two global portfolios: one equal-weighted and the other value-weighted. The return difference is ...
متن کاملThe lunar phases of dust grains orbiting Fomalhaut
Optical images of the nearby star Fomalhaut show a ring of dust orbiting the central star. This dust is in many respects expected to be similar to the zodiacal dust in the solar system. The ring displays a clear brightness asymmetry, attributed to asymmetric scattering of the central starlight by the circumstellar dust grains. Recent measurements show that the bright side of the Fomalhaut ring ...
متن کاملthe study of effective air instability conditions and synoptic patterns on occurrence of dust storms
dust storms are natural phenomena which occur in arid and semi-arid areas of the world. in this study, to evaluate the dust storms which occurred in mashhad over a period of 30 years (1981-2009), first, the number of days on which dust storms happened in mashhad (days with a wind speed greater than 15 m.s-1 and horizontal visibility less than 1000 m) were identified and counted for each month; ...
