... 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. ...

. Quantum clock (atomic clock) - the time measuring device containing quartz generator, controlled by the quantum frequency standard . Atoms play a role of pendulum. The frequency of atoms radiation while the atoms passing from one energy level to another regulates the quantum clock. This frequency is so stable (error 10^-11 - 10^-13) that quantum clocks allow to calculate the time more exactly, then astronomic methods. Back .

In 1848 the Swiss astronomer Johann Rudolph Wolf introduced a daily measure- ment of sunspot number. His method, which is still used today, counts the total number of spots visible on the face of the sun and the number of groups into which they cluster, because neither quantity alone satisfactorily meas- ures sunspot activity. An observer computes a daily sunspot number by multiplying the number of groups he sees by ten and then adding this product to his total count of in- dividual spots. ...
