Problem(s) Encountered:

When using commands 'tx slit/dropleaf close', 
when it was done, would display 'done slit/dropleaf cantopen=rain'; double
checked with the 2.4m operator that it was not raining at that time though.
Rh at 80% by 12pm and has held steady from 87%+ since 12:52pm.

Solution:

This is typical when the humidity is up.  If it causes issues with operating the dome shutter/slit, the TCS can be shut down and restarted to clear these flags.
