Halley's Comet

Abstract

I DO not know if the enclosed is of any general interest or not; it is an attempt to photograph Halley's comet (as seen here) without any special apparatus. The tail was about 90° long on May 17, and probably 115° on May 18, taking the calculated position of the nucleus, which had not risen when dawn came. On May 20 (on the other side) the tail was only 15° or 20° long, but both twilight and moon interfered. It was 35° long on May 23.
