“Light flares ... red orb light up the sky. Those “light pillars,” as the National Weather Service called them, are actually quite rare for the area. “This is an uncommon optical ...

"Flares this large from red dwarfs are exceedingly rare." The star's brightness in visible and ultraviolet light, measured both by ground-based observatories and Swift's Optical/Ultraviolet ...

Using NASA's Fermi spacecraft, astronomers have conducted a long-term monitoring campaign of a blazar known as S5 1803+784 and have identified several gamma-ray and optical flares from this source.

It was so bright that an observer in a dark location could see it with the naked eye. The optical flare radiation from GRB 080319B traced the gamma-ray light curve and hence the activity of the ...

and 1.3m Devasthal Fast Optical Telescopes located in Nainital. The data collected from the flare observed will help calculation of the black hole mass, size of emission region, and mechanism of ...
