Annals of the Astronomical Observatory of Harvard College Volume 4-5 (Paperback)


This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1863 Excerpt: ...clear sky. Definition pretty good. Now that attention is directed to the fact, the impression of a diverging spiral-like radiation of wisps of nebulosity from the bright region near the trapezium is very certain. There are one or two such near a about 1' preceding trapezium, 0/5 south. The three groups of stars constituting the stars of the sword-handle of Orion, c, 0, and c, are foci of nebulous regions. The northernmost has about it a great mass of nebulosity which brightens up around several of the stars. 1861, Jan. 31. Some differences of AR. are given among four stars, of which (c) is c1 Orionis, (d) is cs Orionis, (a) is 536 of the present catalogue, and (b) 614 or 629. This region is brightly nebulous, especially about these four stars, and in the field preceding (c) and (d). About (a) the accumulation of nebulosity is especially marked. Connection can be traced between this nebulosity and that about the trapezium. There is a decided accumulation of nebulosity about a star of 9th Mag. 11' south of the trapezium, and 35 seconds of time preceding it probably H. 34 = 467 of the General Catalogue. All the region for several fields around i Orionis is nebulous. Definition good. Eye-piece and object-glass clear. It is remarkable that about each group composing " sword-handle " of Orion, there is an accumulation of nebulosity quite evident even in the finder. See Obs. Feb. 21, 1863. There are, besides, several instances of a similar preference to the neighborhood of individual stars. The whirl-like arrangement of the drifts of nebulosity about the region of trapezium is very striking to-night. 1861, Feb. 6. Clear, with tolerably good definition. When the attention is given expressly to the dark Chronometer nearly indicating Sidereal time. striae o...
