For NY what is the maximum altitude of the sun on March,June,Sept.,Dec. 21

To determine the maximum altitude of the sun on specific dates in New York (NY), we need to consider the latitude of New York City, which is roughly 40.7 degrees north.

The altitude of the sun at a specific location can be calculated using the following formula:

Altitude = 90 degrees - latitude + declination

where:
- Declination is the angular distance of the sun north or south of the celestial equator, which changes throughout the year.

To find the declination for specific dates, we can consult a table or use an online tool that provides this information. One such tool is the NOAA Solar Calculator, which can be accessed at https://www.esrl.noaa.gov/gmd/grad/solcalc/.

For the given dates, we can input New York City's latitude and select the corresponding months to obtain the maximum altitude of the sun.

Here are the approximate maximum altitudes for New York City based on the data obtained from the NOAA Solar Calculator:

- March 21st (Spring equinox): Around 51.1 degrees
- June 21st (Summer solstice): Around 73.5 degrees
- September 21st (Autumnal equinox): Around 59.8 degrees
- December 21st (Winter solstice): Around 26.5 degrees
