Marty, here is another AUR; AUR(79)r2c79,r6c89,r8c58,r9c57. Both internal and external inferences are readily useable. For posting, I used the external inferences: 9r3c8, 9r5c7, 9r8c4

AUR(79)
9r3c8-(9=7)r8c8;
||
(9-3)r5c7=(3-7)r6c8=7r8c8;
||
9r8c4-(9=7)r8c8; => r8c8=7 to complete the puzzle.

Nice work, Ted. Since my little "vacation", the concept of external inferences hasn't entered my mind.
