RELATIVE SUNSPOT NUMBERS Description of Data from SGD Explanation of Data Reports: Relative Sunspot Numbers -- The relative sunspot number is an index of the activity of the entire visible disk of the Sun. ... The provisional daily Zurich relative sunspot numbers, Rz, were based upon observations made at Zurich and its two branch stations in Arosa and Locarno and communicated by M. Waldmeier of the Swiss Federal Observatory. ... This indicates the uncertainty above and below the predicted number. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

There are two modes to specify the time interval of ephemeris. ... This mode is applicable if the date of opposition belongs to the basic interval of 16 months from November of the year preceding to the title one to February of the subsequent one. In this case the ephemeris is centered at the nearest standard moment (its Julian day minus 0.5 is exactly divisible by 10) which precedes or coincides with the moment of opposition of minor planet in specified year. ...

NAME logresolve - resolve hostnames for IP-addresses in Apache logfiles SYNOPSIS logresolve [ - s filename ] [ - c ] < access _ log > access _ log . new DESCRIPTION logresolve is a post-processing program to resolve IP- addresses in Apache's access logfiles. To minimize impact on your nameserver, logresolve has its very own internal hash- table cache. This means that each IP number will only be looked up the first time it is found in the log file. ...
