👉 In the context of astronomy, a "spellar" is a celestial object that appears as a point or a small pointy spot in the sky. These objects are often associated with eclipses and are used to determine the position of the sun during specific solar events such as a full moon or new moon. For example, if you were observing an eclipse of the sun, you might see a spellar that appears to be "spreading out" or "wiggling" in the sky.
