Glossary:

Lunar Eclipse: The Moon gets eclipsed by the shadow cone of the earth, this may happen at full moon only and during local night.
Penumbral eclipse begins/ends: The moon gets covered by the shadow of earth. For a virtual observer on the moon, the sun is partially eclipsed by the earth. Seen from earth, this phase of a lunar eclipse is only very hard to observ, since the darkening is only very slim.
Partial eclipse begins/ends: The moon gets partially covered by the shadow of earth. For a virtual observer on the moon places in the occulted part, the sun is totally eclised by the earth.
Totality begins/ends: The moon has fully entered the shadow cone of the earth and appears as red colored ball in the sky.
Greatest eclipse: At this moment, the moon is most deeply emerged in the shadow cone.
Magnitude of a lunar eclipse: is the fraction of the diameter of the moon obscured by the shadow of the Earth at the greatest phase of the lunar eclipse, measured along the diameter.
Opposition in RA: The right ascension of the moon is just opposite of the one from the sun.
Eclipse at rise/set: Eclipse starts/ends locally at rise/set of the occulted bodies. Other phases of the eclipse are hence not visible.
Altitude/alt/h: Angular separation of the object from the local mathematical horizon. This accounts for refraction as well.
Position Angle / PA: Angle, defining a position on an apparent disk or the position of a dimmer star with regard of the main star. It is counted around the reference points (center of disk/brighter star) from celestial north direction 0° to east (left) 90°, south 180° to west (right) 270° in counter clockwise direction.
Position Angle rel. Vertex: Angle, defining a position on an apparent disk. It is counted around the reference points (center of disk) from local up, zenith direction 0° to east (left) 90°, south 180° to west (right) 270° in counter clockwise direction.
