An important parameter in the calculation of seismic hazard , maximum magnitude expressed as Momentmagnitudescale is also one of the more contentious. The choice of the value can greatly influence the final outcome of the results, yet this is most likely a size of earthquake that has not yet occurred in the region under study. Image Freqmag.png f mag plot left thumb 200px Frequency magnitude plot The seismic hazard calculation involves a double integration integral over the region, combined with the expected number earthquake frequency of earthquakes, from the smallest to the largest. The integration must close at the maximum magnitude. The figure shows a typical Earthquake frequency plot for a given region. This is a typical plot for continent al interiors. The circles represent actual earthquake data. Note that the dataset is complete for small magnitudes, but becomes erratic for the larger. At about M5, there are no records, simply because the historical record is usually too short. In some cases paleoseismology can fill some of the gap, but this is rare for continental regions. The last part of the curve, perhaps the most important part, can be filled in by inference. This would come from studying similar geology throughout the world using analogs to extend time , or by a study of fault mechanics . For example, large scale studies have been conducted for Stable Continental Regions SCR s , which are defined defined as regions of continental crust that have not experienced any major tectonism, magmatism, basement metamorphism or anorogenic intrusion since the early Creataceous, and no rifting or major extension or transtension since the Paleogene. http earthquake.usgs.gov scitech scr catalog.html Finally there is the common question of what is the maximum magnitude for the whole world. http www.seismo.nrcan.gc.ca questions faq e.php Unfortunately, it cannot really ... s plates plate tectonics , and the possible limits of the various magnitude scales http eqseis.geosc.psu.edu ... more details
Before the advent of photometer s which accurately measure the brightness of astronomical objects, the apparent magnitude of an object was obtained by taking a picture of it with a camera . These images, made on Photographic film photoemulsive film or photographic plate plates , were more sensitive to the blue end of the electromagnetic spectrum visual spectrum than the human eye or modern photometers. As a result, bluer stars have a lower i.e. brighter photographic magnitude than their modern visual magnitude , because they appear brighter on the photograph than they do to modern photometers. Conversely, redder stars have a higher i.e. fainter photographic magnitude than visual magnitude, because they appear dimmer. For example, the red supergiant star KW Sagittarii has a photographic magnitude of 11.0 to 13.2 but a visual magnitude of about 8.5 to 11. It is also common for star charts to list a blue magnitude B such as with S Doradus and WZ Sagittae .

This original system did not measure the magnitude of the Sun . For a more detailed discussion of the history of the magnitude system, see Magnitude astronomy Magnitude . In 1856, Norman Robert Pogson formalized the system by defining a typical first magnitude star as a star that is 100 times as bright as a typical sixth magnitude star thus, a first magnitude star is about 2.512 times as bright as a second magnitude star.

About the brightness of stars the science fiction magazine Absolute Magnitude magazine Absolute magnitude also known as absolute visual magnitude when measured in the standard V photometric band is the measure of a celestial object s intrinsic brightness. It is also the apparent magnitude a star would have if it were 32.6 light year s 10 parsecs away from Earth. In astronomy , to derive absolute magnitude from the observed apparent magnitude of a celestial object its value is corrected from distance to its observer. The absolute magnitude is then equivalent to the apparent magnitude an object would ... of objects to be compared without regard to distance. Bolometric magnitude is luminosity expressed in magnitude units it takes into account energy radiated at all wavelengths, whether observed or not. The absolute magnitude uses the same convention as the visual magnitude astronomy magnitude a factor of 10 sup 0.4 sup 2.512 ratio of brightness corresponds to a difference of 1.0 in magnitude. The Milky Way , for example, has an absolute magnitude of about 20.5. So a quasar at an absolute magnitude ... cannot be directly observed from relatively short distances the absolute magnitude is defined by reference ... magnitude one must specify the type of electromagnetic radiation being measured. When referring to total energy output, the proper term is bolometer bolometric magnitude. The bolometric magnitude can be computed from the visual magnitude plus a bolometric correction , math M bol M V BC math ... parsecs would appear, the higher its absolute magnitude. The lower an object s absolute magnitude, the higher its luminosity . Many stars visible to the naked eye have such a low absolute magnitude ... magnitude of 1.4 which is greater than the Sun s absolute visual magnitude of 4.83 it actually serves as a reference point .

Unreferenced date January 2009 In astronomy , limiting magnitude is the faintest apparent magnitude of a celestial body that is detectable or detected by a given instrument. In some cases, limiting magnitude refers to the utter threshold of detection. In more formal uses, limiting magnitude is specified along with the strength of the signal e.g., 10th magnitude at 20 Standard deviation sigma . Sometimes limiting magnitude is qualified by the purpose of the instrument e.g., 10th magnitude for Photometry astronomy photometry This statement recognizes that a photometric detector can detect light far ... , limiting magnitude frequently refers to the faintest stars that can be seen with the unaided .... For those who lives in the immediate suburbs of New York City , the limiting magnitude might be 4.0 ... Island and the Bronx , the limiting magnitude might be 3.0, suggesting that at best, only about 50 stars might be seen at any one time. From brightly lit Midtown Manhattan , the limiting magnitude is possibly ... at any given time. From relatively dark suburban areas, the limiting magnitude is frequently closer ... nearly as faint as 8th magnitude. Many basic observing references quote a limiting magnitude of 6, as this is the approximate ..., with both youth and experience being beneficial.
