500kHz WSPR - fewer stations around now

500kHz WSPR has gone rather quiet of late with fewer stations on most evenings. So far only M0BMU has reported me tonight, despite my report being pretty strong. A new 500kHz WSPR receiving station this evening is OY6FRA and it would be great if he could hear me 1164kms to the north. This would not be a new DX record but it would be another new country. The OY6FRA club station's antennas are shown on the left.
