Sentences with phrase «in faculae»

The method we favour gives almost identical umbral and penumbral areas and very similar total magnetic fluxes in faculae.

I must stress these are preliminary results and this trend will need to be sustained to have any impact, the negative trends could be a result of background fluctuations in faculae or plage.

There is an excess of H and K emission in the faculae which surround sunspots, and epochs of sunspot maximum coincide with epochs of maximum H and K.

Not exact matches

This object had an almost circular shape, and a light beam came out from its eastern part that crossed the sunspot to the south of the nucleus, producing a shadow on the penumbra that was lost in the large mass of faculae surrounding the eastern extreme of the sunspot.»

«Despite the fact that ACRIM I, ACRIM II, ACRIM III, VIRGO and TIM all track degradation with redundant cavities, notable and unexplained differences remain in irradiance and the modeled influences of sunspots and faculae.

This increase has not been measured by the other satellite measuring at this period (ERBS); b) other indicators of solar activity, which are closely correlated to TSI (sunspot number, faculae, geomagnetic activity) show no trend in that period, either.

Sunspots are surrounded by a rim called faculae, and in this region the temperatures are actually higher than the average solar surface.

In this study, we address the question of whether the observed decrease in the TSI is the result of evolving solar surface magnetism (sunspots and faculaeIn this study, we address the question of whether the observed decrease in the TSI is the result of evolving solar surface magnetism (sunspots and faculaein the TSI is the result of evolving solar surface magnetism (sunspots and faculae).

One explanation for the postulated reduction in solar radiation during the 17th century Maunder Minimum is that the Sun's surface was not only largely devoid of spots and faculae, but also less bright, overall.

In years of maximum solar activity, it is the bright faculae that prevail, raising the levels of both total and UV radiation.

The origin of a slowly varying irradiance component may derive from changes in the solar faculae and / or in the background solar radiation from solar quiet regions.
