It’s a lunar eclipse for the fact that a solar eclipse the moon would be in front of the of the sun blocking out the sun making the earth dark in the spot where it is hitting in the celestial alignment that’s why it’s a lunar eclipse because moon is being blocked by the sun
We know this because the sun, moon and earth are positioned is a way so that the moon is in the shadow of earth
At night, when the Earth is between the Sun and the moon, the moon would appear to be red. Just for future reference, a solar eclipse is when the Moon is between the Sun and Earth.
