Rows count from the top and columns from the left. The rule doing most of the work: no more than two suns or two moons may sit next to each other in a row or column.

1. Row 1 has two suns side by side in columns 1 and 2, so column 3 of that row is a moon.
2. Column 2 has two suns one above the other in rows 3 and 4, so row 2 of that column is a moon.
3. Column 1 already has its three suns, so its open cells, rows 4 and 6, are moons.
4. Column 2 already has its three suns, so its last open cell, row 6, is a moon.
5. Row 6 has two moons side by side in columns 1 and 2, so column 3 of that row is a sun.
6. Suppose row 1, column 6 were a sun. Then row 1 would have its three suns, so columns 4 and 5 of that row would be moons. That would make three moons in a row, in columns 3, 4, and 5 of row 1. So row 1, column 6 is a moon.
7. Suppose row 6, column 6 were a moon. Then row 6 would have its three moons, so columns 4 and 5 of that row would be suns. That would make three suns in a row, in columns 3, 4, and 5 of row 6. So row 6, column 6 is a sun.
8. Suppose row 2, column 5 were a sun. Then row 2, column 6 would be a sun too, because of the = sign to its left. Then row 2 would have two suns side by side in columns 5 and 6, so column 4 of that row would be a moon. Then row 2 would have moons in columns 2 and 4, so column 3 between them would be a sun. That would give row 2 four suns, and it can only hold three. So row 2, column 5 is a moon.
9. Row 2, column 6 is joined by an = sign to the moon to its left, so it is a moon too.
10. Row 3, column 5 is joined by an = sign to the moon above it, so it is a moon too.
11. Row 4, column 5 is joined by an × sign to the moon above it, so it is the opposite: a sun.
12. Row 4, column 6 is joined by an = sign to the sun to its left, so it is a sun too.
13. Row 5, column 5 is joined by an × sign to the sun above it, so it is the opposite: a moon.
14. Row 6, column 5 is joined by an × sign to the moon above it, so it is the opposite: a sun.
15. Row 2 has two moons side by side in columns 5 and 6, so column 4 of that row is a sun.
16. Row 4 has two suns side by side in columns 5 and 6, so column 4 of that row is a moon.
17. Row 6 has two suns side by side in columns 5 and 6, so column 4 of that row is a moon.
18. Column 5 has two moons one above the other in rows 2 and 3, so row 1 of that column is a sun.
19. Column 6 has two moons one above the other in rows 1 and 2, so row 3 of that column is a sun.
20. Column 6 has two suns one above the other in rows 3 and 4, so row 5 of that column is a moon.
21. Row 5 has two moons side by side in columns 5 and 6, so column 4 of that row is a sun.
22. Row 1 already has its three suns, so its last open cell, column 4, is a moon.
23. Row 2 already has its three moons, so its last open cell, column 3, is a sun.
24. Row 4 already has its three suns, so its last open cell, column 3, is a moon.
25. Row 5 already has its three moons, so its last open cell, column 3, is a sun.
26. Column 3 already has its three suns, so its last open cell, row 3, is a moon.
27. Row 3 has moons in columns 3 and 5, so column 4 between them is a sun: another moon would make three in a row.
