Title: The Neupert effect: Comparison of data and theory Author_list: Veronig, A., Brown, J.C., Dennis, B.R., Schwartz, R.A., Sui, L., Tolbert, K. Abstract: I have recently worked on testing the Neupert effect using RHESSI and GOES flare observations. A simple model on the flare energy budget was derived (including nonthermal energy in electrons, the thermal energy in the plasma as we ll as estimates of conductive and radiative cooling losses) and compared with observations. This kind of analysis could be applied to other flares in order to get an idea on the thermal/nonthermal energy fractions. It would be definitely helpful to have also additional information from other instruments on the flare geometry/size and thermal plasma parameters.
