Geometric albedo node of their orbit, and hence lie on the ecliptic. In practice, measurements at small nonzero phase angles are used to derive the parameters which characterize the directional reflectance properties for the body (Hapke parameters). The reflectance function described by these can then be extrapolated to zero phase angle to obtain an estimate of the geometric albedo. For very bright, solid, airless objects such as Saturn's moons Enceladus and Tethys, whose total reflectance (Bond albedo) is close to one, a strong opposition effect combines with the high Bond albedo to give them a geometric albedo above unity (1.4 in the
Albedo One Albedo One Albedo One is an Irish horror, fantasy and science fiction magazine founded in 1993 and currently published by Albedo One Productions. "Albedo One" is widely regarded as the successor to the defunct Irish science fiction magazine "FTL", which was originally published by the (also now-defunct) Irish Science Fiction Association. "FTL" was itself a successor of the Irish magazine "Gateway". "Albedo One" is often credited as holding the position of the "longest running Irish magazine of speculative fiction" and has been billed as "Ireland's answer to "Interzone"." From issue 1, 1993, to issue 12, 1996, "Albedo One" was published
