Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Observatory, 1888, Vol. 11: A Monthly Review of Astronomy The present Companion is very similar to that issued last year. We have again to thank Mr. Denning for the meteor Notes, and M. Loewy for the Catalogue and Ephemerides of Variable Stars; while Mr. Marth has kindly furnished heme rides for physical observations of Jupiter and Mars, an some valuable information concerning the Satellites of Saturn. The phenomena of Jupiter's Satellites and the elements of occultations are extracted from the English 'nautical Almanac, ' the epheme rides of the Satellites of Mars, Saturn, Uranus, and Neptune from the American Nautical Almanac, ' corrections having been applied in the case of the last three to secure accordance with Mr. Marth's ephemerides published in the Monthly Notices.' The list of Binary Stars has been brought up to date. The Fraction of the Year is the fraction which has elapsed at mean noon of the particular day. The Longitude of the Moon's Terminator is given for mean midnight; the letters M. And E. Signifying morning and evening - that is, that the Sun is rising or setting on that particular longitude of the Moon's surface; the sign indicates longitudes reckoned from the central meridian in a westward direction. The angles of disappearance and re appearance for occultations of stars are reckoned from the true north in the direction N. E. S. W., as for double stars, following the precedent of last year. Greenwich Mean Time is used in all cases, and the astronomical day is reckoned from noon to noon as in previous years.
