Desaturating SDO/AIA Observations of Solar Flaring Storms

Dynamic Magnetography of Solar Flaring Loops

We develop a practical forward fitting method based on the SIMPLEX algorithm with shaking, which allows the derivation of the magnetic field and other parameters along a solar flaring loop using microwave imaging spectroscopy of gyrosynchrotron emission. We illustrate the method using a model loop with spatially varying magnetic field, filled with uniform ambient density and an evenly distribut...

Statistical Properties of Flaring and Sub-flaring Activity in the Solar Atmosphere

We review the observational, theoretical, and numerical efforts to interpret the statistical behavior of solar flares and sub-flares, and their role to coronal heating. The observed X-ray flares cannot heat the corona. The role of smaller-scale events is still inconclusive, although very recent observational evidence may shed light to the controversy. Statistical and classical modeling reproduc...

Nuclear Magnetohydrodynamic Emp, Solar Storms, and Substorms

In addition to a fast electromagnetic pulse (EMP), a high altitude nuclear burst produces a relatively slow magnetohydrodynarnic EMP (MHD EMP), whose effects are like those from solar storm geomagnetically induced currents (SS-GIC). The MHD EMP electric field E < 10 V/m and lasts < 10 sec, whereas for solar storms E > 10 V/m and lasts >10 sec. Although the solar storm electric field is lower th...

Multi-Wavelength Observations of 1ES1959+650 in a Flaring State

In May 2002, the BL Lacertae object (BL Lac), 1ES1959+650, was detected in the Very High Energy (VHE) regime by the VERITAS collaboration using the Whipple γ-ray observatory. During the following two months, the VERITAS collaboration observed episodes of flaring; at times, the nightly average VHE signal was three times as bright as the Crab Nebula, the standard candle in VHE astronomy. 1ES1959+...
