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