THE CONSTELLATIONS : Part 3
CULMINATION TIMES


CULMINATION of the CONSTELLATIONS

Culmination dates are when some star or constellation crosses the local meridian and reaching its highest point in the sky. In Table 1 these are conveniently expressed for midnight (12pm) and in the early evening at 9pm, when most observers would be looking at the nighttime sky. To find the culmination times at other times of the year, subtract 15 days for ever hour that is earlier than this date. For times that are later; add fifteen (15) days for every hour. If the date is different than specified, add or subtract twenty-eight (28) minutes for each week that has elapsed or is to come.

This page shows three main tables. These are the culmination times of the constellations and bright stars at midnight (12pm) and the evening (9pm.) Culminations are listed as;
