is the plane coming or going?

Lovely photo as usual Keyan. We don't usually see that here in Australia, I haven't seen it, anyway. It must be the atmosphere in the northern hemisphere.

Not much time for sudoku today.

Hopefully, someone else will provide a proof for this one.

5:37 easy today Maen

Anne i've seen it when traveling up to Geraldton and also across the Nullabor. The planes have to bew at high alt

Good maEn to all
A nice tree
A sun shine
A Quick plane
A nice shot

A gnarly tree. Very interesting shot, with the sun obscured by clouds behind the branches.

Enjoy whatever this day brings to you--cheers,everyone.

(no time, forgot to start it!) Maen!

Ah, poor STEVE grows weary of the yoke and shackles we have placed upon him ... :) (Thanks, Steve!)

Kevin, it's going.

Good afternoon to all! Nice photo Keyan. The optical illusion makes it seem like the plane is coming straight down to the earth. Well done!

Apart from taking a lot of nice pictures, who is Keyan - I don't remember seeing his or her name among the comments? Or am I missing something?

beautiful picture, a tree as a lace

maeN all!

Thanks for the kind comments! I hang around here often, but usually don't comment because I normally do the puzzles late - even the next day.

Judy!

A hasty proof follows...

A proof for tough sudoku of 01 23 2007:

1) Start at 23 filled - the given puzzle. Unique Possibilities to 24 filled. (UP 24).
2) Pair 78 at ch2 forbids adg2=78 and f2=8 UP 25
3) triple 238 at b789 forbids a7,c78,b56=2 and forbids a79,c78,b5=3 and More...

I believe Keyan is a woman from San Francisco.

15:13; Nice shot.

Managed this one without even getting stumped once! Must be an easy 'tough.'

Before the pic fully exposed (and before the popup) I'm thinking 'hmmm a..tree, getting low on material' Of course now I'm thinking 'hmmm a trail, getting l..' KIDDING! ANYhow, Puzzle wasn't too bad. Once I did the usual naked reductions and the pointing pairs, a couple of 2-string kites (or More...

Happy Birthday to me!

KEYAN BOWES: Are you Corie Rolston? I have assumed this for some time based on your pen name. Enlighten me please.

i hope other people & friends said that also

maEn all

I do remember seeing quite a few of Keyan's photos on here way before we started submitting our own, before there were more comments other than times. I was assuming this was a professional photographer whose work Gath had purchased. Keyan is quite the globe trotter!

Happy Birthday Nancy!

16.05 with one guess it must have been easy ...i don't normally get through these

Canuk Greg: I think Keyan and Corie are two different women. Both are writers and both live in the Bay Area. However, Corie is also a scientist at LLL.

23 Jan tough, then why is cell G8 not 3?

finally have time to finish this puzzle tonight.
goodnight everyone

finished w/o any trouble..and a nice pic...thought Keyan is a male..but then my knowledge regarding the names is very poor..so far other than some obvious ones always my guess was wrong!!

Hi Martha
I just like to ask that some friends name which we are not familiar about is Male or Female
So what about putting (F) or (M) To atleast know them without any mistake
Hope

Wagdy: I think some people like the anonymity. I figure people will reveal parts of themselves through the things they say if they choose to. By the way, I'm not sure if Wagdy is male or female. There seem to be several male Egyptian Wagdys on the internet, but could be a unisex name.

tough one...nice pic

Had trouble with this one.

Good one. Took 25 mts.

SE=7.3

not really an improvement: UP=35
1.kraken cell(479)g3 => f2<>5 UP=42
(4)g3-(248=5)cgf6

(7)g3-(137=5)h134-e4=f6

(9)g3-e3=f2
2.(3=267)fgi8-(2)f6=(28')cg6 -(4)g6=gi5-(278')agi5=(7)h5-h3=g3 => g8<>7,g3<>4 STE.
