1.  Data Manager Issues:  No longer starting up, path is incorrect somewhere => Re-installing for a “fresh” start  Solution to dynamic ip issue => Set up router specifically for ldm connection, tied to ip address that USPLN has.  Rachidi et. al. (2004) article => relating experiment data to peak current via statistical means

2.  Transmission line model (simpler than Uman’s): E is the far electric field I current of return stroke v is the return stroke speed r horizontal distance from lighting to observation point c is the speed of light

3.  Hard to solve. V varies with each return stroke, error in v will result in the same amount of error in I.  Used a statistical approach with mean values and standard deviations of E, I, and v: Is the mean Is the standard deviation

4.  Method gives good results when compared to data of r = 5km (rocket triggered)  Can we do a similar method?  Need data of return stroke velocities for further distances and for this region
