The Sun recently emitted two major solar flares, but officials at NOAA said the flares do not seem to have caused Thursday's nationwide outage of cellular service.
It proved possible to identify three event types: impulse flares of a total duration of less than 30 min, typical (two-ribbon) flares of less than one to two hours' duration, and very prolonged events, which include phenomena in activity complexes and dynamical flares. These results are in ...
The effect of solar flares, coronal mass ejections, and co-rotating interaction regions on the Venusian 557.7 nm oxygen green line The Venusian 557.7nm OI (1S - 1D) (oxygen green line) nightglow emission is known to be highly temporally variable. The reason for this variability is unkn......
I.阅读理解Great power of solar flaresFrom keeping us warm to helping our plants andflowers grow, most of us don't give the sun much thought asit sits calmly in the sky, so far away. Yet, it's not always sopeaceful up there.On Sept 4, NASA reported that huge solar storms weretaking...
GPS-TEClow-latitude ionospheresolar zenith angleThe effect of intense solar flares on total electron content (TEC) variability during the declining phase of solar cycle-24 is studied at the low-latitude station at Varanasi, India (Geog. Lat. 25.31° N, Geog. Long. 82.97° E, Geomag. Lat....
MR. BRUCE believes that the short-lived broadening which we observe in the Balmer emission lines during the “flash’ phase of an intense flare arises from a temporary magnetic field of the order of 105 gauss. If this is so, some explanation is needed of
Based on a sample of 1114 flares observed simultaneously in hard X-rays (HXR)by the BATSE instrument and in soft X-rays (SXR) by GOES, we studied severalaspects of the Neupert effect and its interpretation in the frame of theelectron-beam-driven evaporation model. In particular, we ...
3 Effect of an Extreme Solar Flare Solar flares are categorized by the power in the 0.1–0.8 nm wavelength range in the X-ray part of the solar spectrum. The highest category of flare (X) has a power > 10−4 W m−2. The largest solar flare on record is an X28 (2.8 × 10...

"Studies have indicated that the illuminated part of the Earth's ionosphere is extremely sensitive to variations in solar radiation fluxes, which can cause failures in technology that people rely on daily," she said. "During more powerful events, the effect on the...
