  journal={Solar Physics},
We present the analysis of observations of the August flares at Big Bear and Tel Aviv, involving monochromatic movies, magnetograms and spectra. In each flare the observations fit a model of particle acceleration in the chromosphere with emission produced by impact and by heating by the energetic electrons and protons. The region showed inverted polarity and high gradients from birth, and flares appear due to strong magnetic shears and gradients across the neutral line produced by sunspot… Expand
Purely coronal flare-like variations
A detailed study of the quasi-periodical post-flare variations on November 6, 1980 in X-rays, UV lines, microwaves, and metric waves confirms that these variations were predominantly thermalExpand
Flare and filament activation in an unusually distorted field configuration
Using photospheric and Hα observations and total radio flux data we study a two-ribbon flare in AR NOAA 4263 which was a part of a flare event complex on July 31, 1983. We find some facts whichExpand
Source of the solar flare energy
Recent Skylab and magnetograph observations indicate that strong photospheric electric currents underlie small flare events such as X-ray loops and surges. What is not yet certain, because of theExpand
Conjugate Hard X-Ray Footpoints in the 2003 October 29 X10 Flare: Unshearing Motions, Correlations, and Asymmetries
We present a detailed imaging and spectroscopic study of the conjugate hard X-ray (HXR) footpoints (FPs) observed with the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) in the 2003 OctoberExpand
Relationship between magnetic field evolution and major flare event on July 14, 2000
On July 14, 2000 the active region NOAA 9077 produced one of the largest solar flares (3B/X5.7) seen in recent years associated with a violent halo coronal mass ejection (CME). It had a βγδ magneticExpand
Spatial structure and temporal development of a solar X-ray flare observed from Skylab on June 15, 1973
A solar flare on June 15, 1973 has been observed with high spatial and temporal resolution by the S-054 grazing-incidence X-ray telescope on Skylab. Both morphological and quantitative analyses areExpand
Flare-productive active regions
This review focuses on the formation and evolution of flare-productive ARs from both observational and theoretical points of view and shows that the improvement of observational instruments and modeling capabilities has significantly advanced understanding in the last decades. Expand
Flare differentially rotates sunspot on Sun's surface
The sudden flare-induced rotation of a sunspot is reported using the unprecedented spatiotemporal resolution of the 1.6 m New Solar Telescope, supplemented by magnetic data from the Solar Dynamics Observatory. Expand
High-energy observations of solar flares
Extensive observations of solar flares made in high energy bands during the maximum of the present solar cycle are discussed with a special reference to the results from HINOTORI, and with attentionExpand
Flare model chromospheres and photospheres
Homogeneous plane-parallel model atmospheres for solar flares have been constructed to approximately simulate observations of flares. The wings of the Ca II lines have been used to derive flare upperExpand


The solar flares of August 28 and 30, 1966
We describe observations of the class 3+ flare of August 28, 1966, made at the Mount Wilson Observatory. This great proton flare followed the sequence: (1) Precursor flare; (2) Filament eruption; (3)Expand
Magnetic fields, bremsstrahlung and synchrotron emission in the flare of 24 October 1969
An impulsive flare October 24, 1969 produced two bursts with virtually identical time profiles of 8800 MHz emission and X-rays above 48 keV. The two spikes of hard X-rays correspond in time to theExpand
Thick-target processes and white-light flares
Observations indicate that fast electrons in solar flares, which cause the hard X-ray burst and the impulsive microwave burst, lose energy predominantly by collisional processes. This requires aExpand
The directivity and polarisation of thick target X-ray bremsstrahlung from solar flares
The directivity and polarisation of solar hard X-ray bursts is discussed in terms of two bremsstrahlung source models. These involve continuous and impulsive injection of electrons respectively, asExpand
Fine structure of solar magnetic fields
The deduction of magnetic fields from chromospheric structure is extended to active regions and transverse fields. Fields independently predicted by these rules from a high resolution Hα filtergramExpand
A note on chromospheric fine structure at active region polarity boundaries
High resolution Hα filtergrams from Big Bear Solar Observatory reveal that some filamentary features in active regions have fine structure and hence magnetic field transverse to the gross structureExpand
Free-free absorption of gyrosynchrotron radiation in solar microwave bursts.
Abstract : A model for solar microwave bursts is considered in which over a broad frequency band the flux density is a slowly varying function of frequency. It is proposed that such an essentiallyExpand
Analog video magnetograms in real time.
A photographic subtraction of two monochromatic images to produce a picture of the Sun in which the line-of-sight component of the solar magnetic field appears as various shades of gray, and a magnetogram made by this method is shown. Expand
An interference filter for observing the photospheric network
Photographs of the Sun, recently obtained with a violet interference filter (λ ≃ 3840 Å), show the photospheric network (or photospheric faculae) with a contrast of typically 20% across the entireExpand
