Request is to add 11 year solar flare cycle data to the sun integration - used for aurora forecasting and who knows what else! Seems like a natural fit
Other additional parameters may be appropriate especially since they may affect climate, electronic transmissions and who knows what else.
'needs input from a subject matter expert.

original paper by Hathaway et al
there are multiple sets of relevant data that affect Earth but sun spots I think define the solar cycle which is generally proportional to solar flare activity (I think!)
graph is here; I suggest the monthly, smoothed monthly data and predicted data plus maybe some marker for the maxima and minima

thank you!
