Hi Mike,

Yes, the helium is venting to atmosphere now.  The normal boil off is
between 5-15 cc/hr depending on the day and temperature of the room. 
Now it's at 15-17 cc/hr.  The normal daily lost is 0.5-0.6 %.  Now
it's at 0.78% daily.  Normal weekly lost is 4-5%.  Now is about 5-6%. 
I think it has stabilized.  I have the O-ring tape with electrical tape
and keeping record of the boil-off.  I am crossing my fingers and hoping
it doesn't get worst, until we get a full assessment.

Best,
Hla
