I have made observations since LST19:59:40 when the Sunset occured till LST00:40, when the Moon’s eclipse was in the penumbral phase. Few children from the nearest schools were together with me. We observed Moonrise. The disk of the Moon was unobviously orange and encountered by clouds. Moonrise LST 20:58:30. The subsequent 1 hour was obscure due to clouds.

The first contact (P1) at LST22:54:08. The point of contact is plased at 320 Deg on a circular disk (50 minutes on ahand’s clock disk). It was difficult to establish the maximal phase moment due to small magnitude of the Eclipse. It was probably ~ 1-2%. I have noted in my Observations Journal the Time of Maximal Phase at LST23:09.

Since this moment the eclipse is going down (decreasing). Last contact LST23:26.This moment could be uncertain due to some oscillations I have observed during this final stage. Could they be related with Wobble?

The second Penumbral phase could be characterized by a sharp increase of broghtness of the Lunar disk. Unfortunately, some clouds covered the lunar disk during this phase.

At LST 00:22 the Moon has coordinates +10 Deg, H=30Deg above the Horizon. Polar Star cannot be seen due to clouds.

Other observations:

Twilights could be observed after Sunset during about 25 minutes. They were of deep red (bordeau) color.

A 2 motors airship flew from South to North at LST 23:16-LST23:19. The airport was very close and South of Durleshty village near Chisinau.

The observations were made in Chisinau,The Republic of Moldova.
