The weather throughout this year was so extremely favorable that I have been able to observe the Sun clearly on 312 days; however, I counted only 34 groups of sunspots.. From my earlier observations, which I have reported every year in this journal, it appears that there is a certain periodicity in the appearance of sunspots and this theory seems more and more probable from the results of this year.. ...

... Our recent observations with the Hubble Space Telescope (August 29, 2014) led to revealing a highly isolated dwarf spheroidal galaxy KKs 3 situated at a distance of 2.12 0.07 Mpc from the Milky Way.

The most important directives used to control this MPM are ThreadsPerChild , which controls the number of threads deployed by each child process and MaxRequestWorkers , which controls the maximum total number of threads that may be launched. ... Two directives set hard limits on the number of active child processes and the number of server threads in a child process, and can only be changed by fully stopping the server and then starting it again....
