re: By the light of the silvery (super) moon

I had planned on taking some nice photos of the moon last night, but alas, this is the Pacific Northwest of the U.S. and clouds tend to come up whenever there's anything interesting to see. Last night was no exception. I have seen red or orange moons though.The lunar eclipses I've seen tend to give the moon an orange tint. During the summer, forest fires aren't all that uncommon out here and they can cause some pretty spectacular red or orange moons, not to mention sunsets. I haven't seen any other colors though.

The moon is frequently red or orange when it's full and very close to the horizon (as in your 4th photo) - I think due to the light passing through more than usual of the atmosphere due to the slanted view. Never seen a blue one though. I think your 2nd photo was done with a filter....

Hi David -- as you say, it's possible the blue moon image was done with a filter, but I know you really can see a blue moon in the right circumstances.

We got lucky here on the east side of the cascades (still in the pacific northwest) and had enough of a break in the weather that I was able to see the moon and even become mildly annoyed when the light disturbed my sleep. I kept thinking it was time to get up... The third photo is a partial lunar eclipse. You can see the different degrees of shadow from the earth as it passes over the moon. I've seen a couple total lunar eclipses and the moon turns a really deep red. And as Duane mentioned forest fires can turn the moon orange or red.

Hello Max, our Solstice here in southern England (East Sussex) was clouded out but we have since had a lovely peach coloured moon one night. It was quite low down but not hard on the horizon. GAry

LOL

I'd love to see that

Sorry to hear you were clouded out -- but I'm glad you got to see the peach-colored moon. Can you imagine what our distant ancestors must have thought when they saw different colored moons?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
