Why would you want to know? You just need to know how many futures your are delta long for hedging. Why is notional needed unless you are a hedger?
Multiply the delta * the contract value above, $48,500*.23= $11,155. The strike price is not relevant for the calculation. As time passes, the delta will either go to 0 or 100 and adjust for you. Obviously the value will change every time the delta changes.

Correct me if I am wrong... but an out of the money call option has zero notional value until it is in the money... Once its in the money, the notional value is the same as the underlying contract.
The notional value is the value of the investor can control rather than the value of he owns.
