... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...

... The classical Beltrami theorem says that any metric whose geodesics are straight lines has constant curvature. But what can we say about geometries whose geodesics are circles (to be more precise --- parts of circles; by a circle we always mean a circle or a line)? ... We prove that a rectifiable simple bundle of circles containing sufficiently many circles in general position is the image of a bundle of lines under some left or right quaternionic fractional transformation. ...
