    The United States consumes × J of energy each year. A typical solar flare releases × J of energy. How many years could we run the United States on the energy released by this solar flare if all of the released energy could be used? a. 5×10−6 years b. , years c. × years d. about 12 years e. years. A solar flare is a sudden flash of increased brightness on the Sun, usually observed near its surface and in close proximity to a sunspot group. Powerful flares are often, but not always, accompanied by a coronal mass ejection. Even the most powerful flares are barely detectable in the total solar irradiance. Solar flares occur in a power-law spectrum of magnitudes; an energy release of typically joules .

    Solar Flares Interpreting Solar Activity This is an article on the astrology of intense solar activity, the inner or personal effect of solar flares, Coronal Mass Ejection (CME) events, and related phenomena. In my experience the active Sun provides indicators of a different order of magnitude compared to traditional astrological techniques. When. A DYNAMO THEORY OF SOLAR FLARES The dynamo is assumed to be located in the boundary region between the photosphere and the chromosphere, where the Pedersen conductivity is highest (Obayashi, ). The dynamo current I o driven by the neutral wind V. can be written, in MKS units, as (e.g., Fejer, ) I o - - Z ' (E o + V. xBo), (1).

      The electric charge flow into and out of the Sun can sometimes increase to the point where it releases plasma discharges called solar flares. Conventional scientists think that solar flares occur when magnetic loops “reconnect” with each other, causing a short circuit. The so-called “magnetic energy” is said to accelerate gases into space.   This paper outlines the current understanding of solar flares, mainly focused on magnetohydrodynamic (MHD) processes responsible for producing a flare. Observations show that flares are one of the most explosive phenomena in the atmosphere of the Sun, releasing a huge amount of energy up to about erg on the timescale of hours. Flares involve the heating of plasma, mass .

In this book the authors have selected the best observational material from the literature on which to base a detailed account of the properties of flare and non-flare loops. The book also explores the larger implications of the loop structures in our understanding of solar and stellar by: depending upon their orientation with each other.

Collisions between current-carrying loops are considered to be the cause of some solar flares (Sakai & de Jager ). Based on the loop orientations and size of the interaction region, the current-carrying loop interactions are classified into three categories.

The coalescence of a flare loop and a filament is presently used to illustrate magnetic-loop reemergence and the correct application of the generalized form of Ohm's law for solar flares. Flare energy release entails large current values, a nonsteady-state process, and the existence of a neutral component in a flare.

Fig. shows sketches of the two basic paradigms for solar flares: the “simple loop” configuration and the global reconnection configuration. Most flares fall into the first category, although the loops probably contain many filamentary substructures and cannot be “monolithic” as is often assumed; the global reconnection configuration serves well to describe CMEs and their near-Sun Author: H.
