Quotes by George C. Comstock (?)

“and at the very beginning of his study in astronomy”
― George C. Comstock, A Text-Book of Astronomy

“A = T ± U T stands for the time by the clock at which the star crossed the meridian. A is the right ascension of the star, and U is the correction of the clock. Use the + sign in the equation whenever the clock is too slow, and the - sign when it is too fast. U may be found from this equation when A and T are given, or A may be found when T and U are given. It is in this way that astronomers measure the right ascensions of the stars and planets.”
