so ive been watching the solar flux numbers creep up over the past few weeks and finally decided to actually sit down and see what 10m was doing yesterday afternoon. honestly wasnt expecting much because every time ive checked lately its been dead as a doornail but wow was i wrong. started hearing stations from europe coming in around 1400 local and by 1600 i had worked a handful of italians and a couple spanish stations without even trying that hard, running like 100 watts into a wire dipole up maybe 25 feet.

flux was sitting around 185 or so which i guess is pretty decent for where we are in the cycle. i know we're supposed to be heading toward solar max but i honestly havent been paying close enough attention to know how good it can really get. is this kind of opening normal for this flux level or did i just get lucky with the right ionospheric conditions? and does anyone have a good way to predict when these things are gonna happen, ive been looking at DXMaps but sometimes the spots show up and the band is already dying by the time i tune around

185 is pretty solid, you're right to be excited about that. when the flux gets up into that range 10m can open to europe from the US east coast almost daily, usually right around the time you described. the thing people dont always realize is that the flux number is kind of a lagging indicator in a way — what actually matters in the moment is the K index staying low. if you've got decent flux but the K index spikes up from geomagnetic activity you can kiss those openings goodbye real fast.

for predicting it, i honestly just check the space weather center page in the morning and if flux is above 150 and K is 2 or under i make a point to check 10 and 12m during the afternoon. DXMaps is great but yeah the cluster spots can lag, sometimes by 10-15 minutes which on a marginal opening is basically an eternity. try WWV on 10 MHz if you want a quick gut check on conditions, they broadcast the solar data every hour.

dude i had almost the exact same experience last thursday. i'm still pretty new to HF (only been licensed about 8 months) and i had basically written off 10m as useless after checking it a few times and hearing nothing. but my buddy at the club told me to just leave it on in the background and wait and sure enough one afternoon it just kind of exploded with signals. worked my first ever DX on that band, a station in Portugal. still kinda cant believe a wire antenna did that
