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