Abstract: An error in the program for verifying the Ankeny-Artin-Chowla (AAC) conjecture is reported. As a result, in the case of primes $p$ which are $\equiv5\bmod{8}$, the AAC conjecture has been verified using a different multiple of the regulator of the quadratic field $\mathbb{Q} (\sqrt{p})$ than was meant. However, since any multiple of this regulator is suitable for this purpose, provided that it is smaller than $8p$, the main result that the AAC conjecture is true for all the primes $\equiv1\bmod{4}$ which are $<10^{11}$, remains valid.

As an addition, we have verified the AAC conjecture for all the primes $\equiv1\bmod{4}$ between $10^{11}$ and $2\times10^{11}$, with the corrected program.
