The premium (or cost) for Solstice flares is pretty easy to eyeball because there are two markets live: USX and eUSX. eUSX 7D trailing APY 6.34% eUSX implied APY 7.30% 15x flares cost = 0.96% USX 7D trailing APY 0% USX implied APY 4.88% 30x flares cost = 4.88% The only caveat, is that eUSX underlying yield fluctuates, the 1D shows 5.47% and if it were to drop that low than it’s more closely priced to USX flare cost.

The Sun emitted two strong solar flares, the first peaking at 9:07pm ET on April 23 and the second peaking at 4:13am ET on April 24. NASA’s Solar Dynamics Observatory captured images of the events, which were classified as X2.4 and X2.5: Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel.
