Astronomy Update September
Not much of any significance this month, so we will do some basic stuff if you like
New moon (no moon visible) was on the First and Full moon will be on the 15th - If you are planning on looking at the moon during a clear spell in the weather the best time is not at full moon as it is so bright all you will be able to pick out are the dark bits (seas) - the best part of the moon to look at is the terminator ( no not Arnie) - this refers to the part of the moon where The sun is either rising or falling and it sends the craters into stark contrast. The lovely thing about the moon is that each night you get a new show as a differnt part of the moon is put on display - If you are watching through a telescope over a few hours you can actually see the shadows of the mountains change as the sun comes up/down.
The Seas of the Moon
Each of the lava flooded plains of the moon is given a name - here is a quick resume for you
Traditionally people in the west see a Face in the moon ( man in the moon) whilst Eastern cultures see a Rabbit ( bottom right)
The phases of the moon
Some people get confused by this - clearly the moon is always there and you are just seeing a different amount of the moon illuminated directly by the sun. Waxing - bright bit getting bigger /waning bright bit getting smaller
For example if you were to look up a few days after a new moon you might see
where the right side of the moon is lit by the setting sun to the right of the picture.
However let your eyes get dark adapted and you will see the rest of the moon Illuminated by light reflecting from the Earth
