Sky Charts for Strongly Light-polluted City Environments

Sky Charts for Strongly Light-polluted City Environments

With the high buildings in Manhattan, you won’t be able to see Regulus from most street-side locations there; the view of the star will be blocked by the buildings, or by glare from nearly ubiquitous street lights. Find a park, or school with an athletic field, where you might have an unobstructed view of Regulus without blinding lights nearby, but certainly, select a safe location. If you can get above the low-level lights, either on a rooftop or from a high westward-facing apartment, you should be able to see Regulus more easily and more stars than are on these charts; in that case, use these charts instead, also useful for the darker locations in large parks.

As shown in these charts, only the brightest stars will be visible; Leo can hardly be recognized as a constellation, with maybe only Regulus visible of the “sickle”. Low in the west, Jupiter and Procyon should still be seen, if they are not obstructed by trees, buildings, or lights; hopefully, the twin stars Castor and Pollux, above very bright Jupiter, will be above any obstructions to help serve as a guide; in the sky, Regulus is roughly halfway between Jupiter and Mars. Mars is the bright reddish planet to the right and above the Moon, with the contrasting but fainter bluish-white star Spica nearby.

You won’t see the names, or any lines, in the sky. What you will really see is more like the second view (but short red lines mark Regulus; of course, they won’t be in the sky).  Printer-friendly versions of both charts (inverted colors, black stars on a white background) are at the bottom (the short “Regulus” marks are blue).
