Sky Watch: Old Moon and Morning Star (2)

I missed Skywatch completely last week and am late this week ... but better late than never, isn't that what they say? Here's the sky Tuesday morning - the new old moon and the morning star.

That picture was not taken on Sunday, May 24, 2009 since a Waxing Crescent moon is not visible before dawn.

First, it wasn't taken on Sunday, nor does the post say it was.

Second, that sounds a lot like the old "full moons always rise at sunset" stuff, which is flat not true. I've seen plenty of full moons well up in the east when the sun was still out - like the last one we had. Since the moon manifestly doesn't orbit faster during the winter, its rise and set can't be synched to the daylight, which is much shorter then.

If the picture was posted on Sunday 24-May, and it says it was taken on Tuesday, that can only mean 19-May, when the moon was not new but quite old. In Baltimore MD that day, the moon rose at 2:40 and the sun at 5:49.

The last Tuesday with a newish moon before 24-May was 28-Apr; the sun rose that day at 6:11 and the moon at 8:37. So that doesn't work either.

Okay, maybe it was an old moon, then.

I took the picture. I'm not an astronomer.
