We spent more time at Cathu’s mom’s house today. David and Maggie are on their way home and Dorothy leave tomorrow to go back to Massachusetts but we were able to straighten up a few things and bring the items Dorothy wanted back to our house. It was warm and the house still has no air conditioning but the contractor is scheduled to come on Thursday to put in a new one. Shortly after we got home it started raining and there was a rainbow. I took a few pictures of that, although they didn’t turn out terribly well. Then a little later, as the sun set, there were some pretty clouds. They were losing their color by the time they got near enough to the moon for a picture, but a few made it before the color was entirely gone.

A little over five weeks ago I posted a picture of a waxing crescent moon, seen through trees and taken from my mother-in-law’s house. Today’s post is a waxing gibbous moon, although seen through tree branches but this time taken from out front yard. I had been out taking pictures of Eranthis hyemalis (winter aconite) and then noticed the moon. So, you’ll have to wait for another flower picture in favor of this one. The moon is nearing full and was quite lovely against the darkening blue of the sky and set off by the branches of a red oak tree (Quercus rubra) in our front yard.
The new moon was four days ago, on January 16. The synodic period (the amount of time between full moons, or new moons or whatever) is 29 days, 12 hours, and about 44 minutes. The sidereal orbit (the orbit around the earth without regard to the relative position of the sun) is a little more than two days shorter than that, of course. In the time it takes the moon to circle the earth, the earth has moved almost one twelfth of the way around the sun and it takes the moon that extra two-plus days to get back into the same position relative to the sun and the earth. During the first quarter of the cycle, the moon is a growing (waxing) crescent (less than half visible). The second quarter it is waxing gibbous (more than half visible).
As you probably learned in school, the moon’s orbit around the earth is not circular but elliptical. On average, the moon is 385,000 kilometers (239,000 miles) from earth but tonight is was at perigee, that is at the closest point in its orbit to the earth, and 357,492 km (222,135 miles) from earth. It’s also near syzygy, which is when the moon, earth, and sun all line up (which is when there is a lunar or solar eclipse). Because it’s not exactly at syzygy, it’s just a bigger than normal full moon. George loaned me his telescope a while back and I got it out this evening to see if I could get anything worth while. I bought a t-ring adapter and this is my first chance to use it.
The moon is just past full and with the clear skies we’ve had lately, the moonrise has been wonderful to see. Here is the waning gibbous moon as it rose this evening.
