What coordinates would I use to communicate a fixed position on the celestial sphere or Equatorial Grid?
Right Ascension & Declination

What months are the two solstices and equinoxes?

What are the 3 different types of solar eclipses?
Total, Partial, Annular

What is the reason we only see one side of the moon? Explain fully.
The moon is tidally locked, because of the synchronous orbit. The moon rotates on it's axis one time for every revolution around the earth.

North or south pole

Explain using specific terms, why a total solar eclipse can only be viewed from very limited positions on earth when it occurs?
The umbra that is created by the moon being in between the sun and earth but crossing the ecliptic plane, cast a very small point onto the earth. Because the moon is only 1/4 the size of the earth it will cast a small shadow onto earth during an solar eclipse.

The location of this celestial object is 10h 40m RA & +49 degrees of Dec. Is this object above or below the celestial equator? Explain why.
Above. Because the declination is positive, this tells us that the object can be viewed above the celestial equator.
500
In the northern hemisphere, as we approach the winter solstice what do we notice about daylight and night? Explain how this happens.
As we approach the winter solstice, daylight hours decrease and are less than the amount of night time hours. This is because the axial tilt of Earth being away from the sun. Therefore, the sun will rise and set south of East & West.

Explain how a "blood moon" or total lunar eclipse experiences it's red color.
As the light from the sun hits the atmosphere of the earth, all other light in the visible spectrum will be scattered or refracted besides light in the red wavelength. This red light is projected onto the moon giving it the "blood" like color.
500
What is the reason that Eclipses do not happen every month?
The moon's orbital path is 5 degrees off the ecliptic so they will only align on rare occasions.
