Wow...what a nice view to start the day.

Oh! Very pretty!

Have a great day everyone!

A yellow, not golden sunset.
Mother nature can get away with painting her sky any color she wishes, but if I were to paint a watercolour of this they'd say, "Why'd she paint it yellow?"

Very nice, Sue.

I don't know if I've ever seen a yellow sky ... we had a wispy pink one the other night, though. Very pretty.

1. Unique possibilities to 28.
2. If g8=6,b8=3=c2,h2=2;23 have no place at g7.So e8=6,pair 69 at f13,f4=4.UP30.
3. If c2=2=a5,b1=3=e2,b3=7=f2,a8=8=b4=f6;column e is devoid of 8.Hence h2=2.UP31.
4. If e1=4,e2=3=b1,c2=1=a9,a5=5 and e3 has no candidate.So e3=4,pairs 28 at a38 and c3 and UPs to 81.

>1 hr -- made a silly error in set up :(

1) Start at 23,basic techniques to UP=29
2) (7=248)abc3-(4)e3=(4-3)e1=(3)b1,=>b1<>7.UP=30
3) Loop:(5=248)a358-(4=5)e3-f2=(5)f5,=>bc3<>4,e2g5<>5.UP=35
4)(8)b4=e4-(8=5)f5-(5=7)f2- (7=3)e2-e1=(3)b1,=>b1<>8.UP=81

Hi Alfred,
1)UP to 29 (+f4=4)
Regards,Sotir

We are getting a lot of yellow in our sunrise/set. The farmers here are all burning off the winter grass & the smoke changes the colours.

Thanks Sotir.Didn't notice the 69 pair at f13 at that stage.Regards,Alfred.

Basic techniques to UP29. Then
1) forbid 7 from b1, (like Sotir)
2) forbid 3 from c2, (4 in b1 creates a 589 triple in b46+c4, and column a runs quickly into trouble then)
3) forbid 4 from c6 (same 589 triple + a little bit)
=> UP81

28:58

SE=8.3

1.SSTS to UP29
2.(3)b1=(3-4)e1=(134')ab1c2 >> -(78)b1 >> UP81
