At the Astronomy Picture of the Day site for January 4, a stunning photo of a green flash which also captures the blue end of the spectrum.
If you go to the site later, you can find the picture through the archive link at the bottom of the page.
Warning: do not read the explanation if you want green flashes to remain magical.
Karl - more proof for your wife that you're not crazy; at least about this

| Eh, Konabob - remember the green flash we saw on Maui at Mark's as the sun set and the whales were splashing about? See you at Aloha Camp next month! |

Ben,
Thanks for that nod. I tried to explain to her last week (stayed 10 days south of Capt. Cook) about the green flash ("I know, you've told me dozens of times already"). But, Honey, I..... "I know, you saw one on Molokai...are yo sure you're all right?"
We looked every night, but no luck. I like your photo better than the one on the link, but that is a really neat site. My wife (8th grade science teacher) will find it useful, and it will VINDICATE ME!!!!!
BTW, do you still have that photo you took? I'd love to have a copy if possible.

Back in the 70's I lived on the beach in Santa Monic, CA. I did a lot of sunset viewing, and I'd guess I had a success ratio of about 35%. Don't know why. |

Slipry1; anyting to do with what you were smokin'?
Konabob, I enjoyed the session as well. Let me tell everyone here, this Konabob guy has his stuff together. I brought two new ukes with me toKona,with the intention of giving my daughter (also visiting) a choice between the two for Christmas. She does not play, but I gave my son one so I thought she might like one; Turns out she decided an instrument should be in the hands of a musician, not on someone's wall as a keepsake, so I ended up with two ukes to take home as well. I met Konabob at Sam's uke shop in Holualoa and brought the two ukes with me for Sam to critique as I had noticed a buzz in one and a weird intonation thing with the other.
The intonation problem is one i have never come across. Often, when I first set up a guitar I find the twelfth fret sounds a bit higher in pitch than the open string; usually a factor of either the nut or saddle being too high, easily remidied by setting the action up (down) properly. Well, on the tenor uke, all strings ended up spot on from open to twelfth fret, except #1 string, which was LOWER at the twelfth fret, rather than higher. I re-filed the saddle to compensate the string to have a shorterlength, but even that did not fix it.
I showed it to Sam, he was baffled. But Konabob tried something; he did this on each string,starting with the 4th; press at th12th fret and pluck over the soundhole, then press above the 12th fret and pluck the neck above the 12th fret. It gives you the same sound, or very very close. When he got to the 1st string, the note above the 12th fret was flat, as before, and the note behind teh 12th fret was sharp!> He deduced the problem was a difference in the mass of that particular string at each end and recommended a sring change.
When I got home i removed the string and reversed its direction, putting the nut end at the bridge, etc.. The test showed the opposite effect; the note above the 12th fret was now sharp, the note behind was flat. Then I took the string off and replaced it; what do you know, perfect pitch both sides of he 2th fret.
Thanks Bob, you hit the nail on the head. I also lowered the action and got rid of the buzz in the concert uke, so all is well in the north country.

Konabob,
I measured that string's diameter at each end today; varied by 8 thousandths from one end to another (over 17 inch scale length)!!! I wrote the company to see what they have to say. |
