Here we present a nearly circular white-light flare on 10 March 2015 that was well observed by the Optical and Near-infrared Solar Eruption Tracer and Solar Dynamics Observatory. In this flare, there appear simultaneously both impulsive and gradual white-light kernels.

May 21, 2010 · The flashes of white light accompanying some solar flares are caused by the sun's acceleration of electrons to speeds greater than half the speed of light. The phenomenon's new explanation...

White-light continuum emission is sometimes observed, and these flares are then called “white-light flares” (WLFs). Aims. We investigate if all flares are WLFs and how the radiated energy is distributed spectrally.

The TRACE "white light" data differ from all previous observations, in that a special UV-sensitive coating on its CCD allows it to observe far into the ultraviolet. This part of the spectrum has never before had adequate photometric observation.

Jan 23, 2024 · White-light flares (WLFs) are the flares with an enhancement in the optical continuum or integrated light (Švestka, 1970; Neidig, 1989; Hudson, 2011). Although the first flare observed in 1859 was a WLF (Carrington, 1859; Hodgson, 1859), the number of …

Jul 20, 2023 · We present an X1.0 white-light flare on 2022 October 2 (SOL2022-10-02T20:25) observed by the Chinese H α Solar Explorer that provides two-dimensional spectra in the visible light for the full solar disk with a seeing-free condition.

Dec 15, 2017 · Recently, many superflares on solar-type stars have been discovered as white-light flares (WLFs). The statistical study found a correlation between their energies (E) and durations (τ): , similar to those of solar hard/soft X-ray flares, .

Dec 6, 2023 · White-light emission has also been observed in off-limb solar flare loops. Here, we perform a suite of one-dimensional hydrodynamic loop simulations for M dwarf flares inspired by these solar examples.

A white-light flare, to introduce the subject, is one that can be observed in the visible continuum. Often this means simply a flare observable in a broad continuum band, as in the original observations by Carrington ( 1859 ) and Hodgson ( 1859 ).

Dec 19, 2017 · Here we present a nearly circular white-light flare on 10 March 2015 that was well observed by the Optical and Near-infrared Solar Eruption Tracer and Solar Dynamics Observatory. In this flare,...
