To enhance the quality and near real time production of K-based planetary magnetic activity indices, such as\udam, and longitude-sector indices, aλ, there is a requirement for local three-hourly K index values from the South\udAtlantic observatory at Port Stanley. We describe the computer algorithm used to estimate the solar regular\udvariation, SR, and techniques used to establish the parameters required to derive the K indices. We analyse the\udresults by comparing the distributions of K values with observatories at similar geomagnetic latitude and thus\udwith likely similar levels of geomagnetic activity. We also look for biases by comparing the indices directly to\udthose from nearby observatories. Both sets of results show a good overall agreement. However adjustment of\udinput parameters will be necessary if improved agreement with the indices from the other observatories is\udrequired
