May I also be the second to second the congratulations fellicitated above.
I still remember vividly my first solo. I can tell you the exact time, date, aircraft reg, weather, cloud, wind, even what the instructor said as the bounded off the wing with a cheery wave. Everything about that day was golden, and I guess the shame is that I will never get the same sense of elation that I had that glorious day. Enjoy the moment.
