# August 2017 Puzzle Periodical - Solar Scramble

By James M., NSA Operations Researcher

## Can you reattach the sun's rays in this month's Puzzle Periodical?

### Problem:

In anticipation of next week's solar eclipse on Monday, 21 August 2017, this month's NSA Puzzle Periodical asks: Can you solve this logic challenge to help reattach the sun's rays?

Due to bizarre and unexplained cosmic fluctuations, the sun's rays have fallen off. In order to save summer you have to put them back on in the right way. Here is what you know:

1. Each of the 10 rays is uniquely labeled with a number in the range 1-10.
2. The spots between the rays are marked with the absolute difference of the ray labels that are next to them.
3. There are four consecutive rays that have even number labels.

Following the above rules, label each spot on the sun with the number of the ray that goes there.

Once the rays are correctly placed, add up the label values of rays that are directly opposite each other on the sun. Convert these values to letters using the substitution 1=A, 2=B, …, 26=Z and read them clockwise starting at the top to find out what the sun can do now that it has its rays again.

### Solution:

Converting to letters:
19 = S, 8 = H, 9 = I, 14 = N, 5 = E
