| 7:03 am Sun, Dec 31 | Penumbral Eclipse begins The Earth's penumbra start touching the Moon's face. Moon close to horizon, so make sure you have free sight to West-northwest. |  298° | 2.6° | |
| 7:20 am Sun, Dec 31 | Maximum in Longmont This is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in Longmont.

How to use altitude & direction to find in the sky
The curvature of the shadow's path and the apparent rotation of the Moon's disk is due to the Earth's rotation.
The total phase of this lunar eclipse is not visible in Longmont, but it can be observed there as a penumbral lunar eclipse. A penumbral lunar eclipse can be a bit hard to see as the shadowed part is only a little bit fainter than the rest of the Moon.
