Some useful references:
1. Stars Over Hawaii by E. H. Bryan, Jr., was first published in 1955 by a company
called BOOKS ABOUT HAWAII, but is long since out of print. A somewhat revised
version has been reprinted by The Petroglyph Press, 201 Kinoole Street, Hilo, Hawaii, in
1977. It is still available in some book stores. Mr. Bryan, as a Curator of the Bernice
Pauahi Bishop Museum in Honolulu was a fount of knowledge on many subjects related to
Hawaii and the Pacific area. Although not a professional astronomer, he was one of the
early active amateur astronomers in Hawaii and a frequent observer of variable stars at the
University of Hawaii's observatory in Kaimuki. In 1955 there was no source of basic
information about the sky as seen from Hawaii and so Mr. Bryan filled a much felt need by
writing this 48-page booklet about the Sun, stars, and planets as seen from Hawaii. Two
sections of this booklet relate to the topics discussed in this paper. One has to do with
how the Sun appears to move. Here he makes use of the polar plot to show the apparent
path of the Sun in altitude and azimuth. In our Figures 7a to 10a we have borrowed this
idea from him. In another section he discusses the situation when the Sun casts no
shadow. Here is an interesting diagram showing the daily northward progression of the
Sun over the islands during May and June. Anyone interested in Hawaiian astronomy will
find this a useful addition to one's library.
2. Astronomical Phenomena for the Year 2001, or for succeeding years, is prepared
annually by the Nautical Almanac Office, United States Naval Observatory, and jointly by
Her Majesty's Nautical Almanac Office, Royal Greenwich Observatory. It is available
from the U.S. Government Printing Office, Superintendent of Documents, Washington,
D.C. 20402-9329. This approximately 80-page booklet contains much useful information
for observational astronomy, including tables of sunrise, sunset, twilight, and day-by-day
tabulations of the equation of time and the declination of the Sun. For exact work, the
graph of the equation of time (Fig.6) in this paper is not sufficiently accurate and the
tabulation in this booklet will be useful. This booklet is abstracted from a much more
comprehensive compendium of astronomical data called The Astronomical Almanac,
published annually by the Superintendent of Documents.
3. Time in Astronomy, Edmund Scientific Company, Barrington, N.J. 08007. Popular
Optics Library No. 9054. Published in 1966 and reprinted in 1980; now possibly out of
print. Written for the amateur astronomer, this booklet describes the various kinds of
solar time and sidereal time, how to make time conversions, and how to locate
astronomical objects in the sky. Many useful diagrams.
