    Lowered long-period response for ?H1 STS-1 channels. The ?H1 STS-1 channel started experiencing harmonic oscillations in early December 2011. There may be a loss of vacuum on the STS-1 channels and water getting into the vault. Vault repair work is being planned. LN2 channel appears to be bad. The problems were resolved May 2014.
