Astronomical Almanacs for SALCs

The following charts graphically show when a section of the sky is above a certain altitude (i.e. 30 & 50 degrees above either horizon). The thick black line shows when the area is transiting the meridian. SALCs are Search Area Location Charts sectioning off areas of the Milky Way used for nova hunting.

Overlaying the three twilights will clearly show when the area is visible in the evening after astronomical twilight and before Central Park closes at 1:00 AM.

The pink upright lines represent the beginning of at least 1 hour of viewing time before the park closes or when the area is between 30° & 50° shortly after astronomical twilight. This is considered a 'season' and exists both when the area is rising and when it is setting.
