We acquired Johnson BV photometry of the binary Be disk system \delta Scorpii during its 2009 , 2010 , 2011 , and 2012 observing seasons and used it to probe the innermost regions of the disk .
We found that several disk building events have occurred during this time , resulting in an overall brightening in the V -band and reddening of the system .
In addition to these long-term trends , we found cyclical variability in each observing season on timescales between 60 and 100 days .
We were able to reproduce the changes in the magnitude and colour of \delta Sco using our theoretical models and found that variable mass-loss rates in the range 2.5 - 7.0 \times 10 ^ { -9 } M _ { \sun } / yr over \sim 35 days can reproduce the observed increase in brightness .
