Hello All,
There is a partial lunar eclipse today. But it will be very difficult to observe.
The greatest eclipse will be at 1:37AM (after today midnight).

A lunar eclipse happens when the long shadow of Earth touches the moons face. Earth’s shadow has two parts: a dark inner umbra and lighter surrounding penumbra. The moon does go into the darkest part of Earth’s shadow tonight, the umbral shadow, but only briefly. Thus tonight’s eclipse is an extremely shallow partial lunar eclipse, with only the northernmost portion of the moon passing through the Earth’s dark shadow for about 27 minutes. At the greatest eclipse, the Earth’s dark shadow will cover less than 1.5% of the moon’s diameter.
