Fluke–or One off..?

Since about May 26th the 6 meter band has been opening up.  A little here and a little there.  There was a rather good opening on Memorial day 2021-05-31.  I was in making contacts as best I could.  I have a very simple antenna (home made OCFD hidden low in the pine trees) that tunes up fine on 6 meters.  On that day I made over 38 contacts with out trying hard and filled in several needed states.  I was a little disappointed when I found that one of my states, ME, does not use LOTW and that is my confirmation method.  I suppose I could send a card and then get it confirmed but I might get another ME before that all happens.  I am now up to 41 states confirmed on LOTW via my “less than adequate” antenna for that band.  I wrote a piece on that same day about all the contacts Condx and Persistance.  toward the end of the day I got this and thought “OH Boy”  

But try as I might he never came back up, in face was not seen by anyone else chasing that I saw.  Might have been a one off occurrence but sure would like to get that in the log.
