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