The first ETA of the morning was seen at 08:36 UT.  The best ETA was at 08:57 UT mag -3 yellow; two second train; very long; ended 4 degrees beyond Arcturus.  This was the longest and brightest ETA I have ever seen.  Second best ETA was at 09:33 UT mag -2 white; one second train; going toward Sagittarius.  Possibly might have seen one or two faint ETA's if sky had been better?  All the ETA's seen this morning had a least a brief train.
