Since this site uses the N0NBH feed, it is impossible for them to be different. Try reloading, you may be looking at a cached page.
It is possible and happens quite often... I understand what you mentioned about reloading the web page. I do that whenever I see a difference from the N0NBH number, but I still see higher solar flux numbers on the solar ham site (more often than not).
Cycle is looking to fall squarely in the "low cycle" group. Of course it could go anywhere from here, but my bet is still that we may have already seen the highest average monthly sunspot number for this cycle.
Looking at the trend, cycle24 is peaking this year and would not be surprised if it has peaked allready!Solar cycle 24 started late ramping up and maybe December 2012 could be the indication from the sun worshippers_Mayas) that a new era will start? Maybe a greater cycle we do not see or have not experienced coming? Surely something is different that's for sure and I do not feel very comfortable!!!
