A sophisticated scam promising a night in a stargazing dome in North Yorkshire catches people out.
Apparent magnitude (m) is a measure of the brightness of a star, astronomical object or other celestial objects like artificial satellites. Its value depends on its intrinsic luminosity , its distance, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer.
The Bortle dark-sky scale (usually referred to as simply the Bortle scale) is a nine-level numeric scale that measures the night sky's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution .
Stars in binary systems (or other multiples) are listed by their total or combined brightness if they appear as a single star to the naked eye, or listed separately if they do not. As with all magnitude systems in astronomy , the scale is logarithmic and inverted i.e. lower/more negative numbers are brighter.
What do email phishing scams look like? They're not as easy to spot as you'd think. These emails often look like they're from a company you know or trust, the FTC says. Meaning, they can look like ...
[8] [9] Every interval of one magnitude equates to a variation in brightness of 5 √ 100 or roughly 2.512 times. Consequently, a magnitude 1 star is about 2.5 times brighter than a magnitude 2 star, about 2.5 2 times brighter than a magnitude 3 star, about 2.5 3 times brighter than a magnitude 4 star, and so on.
A demand of money is then made, though usually the scam is either a bluff (e.g. the scammer never intended to publish them) or the pictures/videos are published regardless even if the money is sent. [1] Sextortion (a portmanteau of sex and extortion) employs non-physical forms of coercion to extort sexual favors from the victim.
(The S 10 unit is defined as the surface brightness of a star whose V-magnitude is 10 and whose light is smeared over one square degree, or 27.78 mag arcsec −2.) The total sky brightness in zenith is therefore ~220 S 10 or 21.9 mag/arcsec² in the V-band. Note that the contributions from Airglow and Zodiacal light vary with the time of year ...
