With and Arrow antenna and 50w you should be able to work W5UN, KB8RQ, RN6BN
and might be a few more with a lot of patience and good EME conditions.

The smallests station I have worked via the Moon was using only a 5 elem
Yagi at the balcony and 50w, but with my 8x17 2M5WL usually a longer Yagi
(3WL or so) and/or 100w are required to be able to make the QSO. Very often
stations with small 4 or 5 element antennas are reporting to copy me via the
Moon, but copying them with their 50w is another matter.

If someone is interested to try EME with me someday just let me know. I'm
always looking forward to meeting new stations via the Moon.

For knowing which stations are CQing at a certain moment, apart from the
already mentioned N0UK EME chat, I could also suggest you look at the Live
CQ page http://www.livecq144.com/
