AB: New Mexico Tech's three-dimensional Lightning Mapping Array (LMA) is being operated in a compact configuration at Langmuir Laboratory. Eight of the twelve mapping stations are deployed within a 4-km diameter area around the mountain laboratory and the system is being operated in high time-resolution mode, allowing sources to be located in successive 10 microsecond windows. The relatively small size of the array together with the high time resolution will allow us to study close lightning flashes in great detail. The data are augmented with `fast' and `slow' electric field change recordings of the lightning, also beneath the storm. The combination is to be used for detailed studies of lightning discharge processes, examples of which will be presented. 400-microsecond time resolution data from the mapping array are processed in real time and made available on the web at http://lightning.nmt.edu/ll\_lma. This allows us to monitor storms as they develop and to facilitate other research activities such as balloon flights into the storms. An interesting result of having a compact array is that the mapping network locates the sources of strong corona from power lines on the plains around the mountain.
