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 generally ranged from largely positive to very positive. One reviewer stated that "if you're flatulently full with the fluffer shorts of pedestrian writers going through the motions, a dose of "Albedo One" #29 is the perfect antidote." The same reviewer stated of issue 32 that ""Albedo One's" inexorable rise to the top gains momentum with this issue's expertly assembled and fluid mix of speculative fiction." A review of issue 33 on BestSF stated of the magazine that "It's not quite up to kicking "Interzone's" arse, but as the redoubtable English mag takes strides forward under its new leadership, "Albedo One"
