We compare observational signatures of two GOES C8-class solar flares through instrumentation on Solar Dynamics Observatory (SDO). Data from the Atmospheric Imaging Assembly (AIA) and the Extreme Ultraviolet Variability Experiment (EVE) provide a unique look at the sun through global scale, fast cadence, high-resolution photometric and spectral measurements; this data is ideal for analyzing the temporal evolution of flare properties. The two flares studied differ in both time scale and morphology, one may be classified as a long duration event (LDE), while the other is highly impulsive. Differences are noted in behavior in the AIA EUV bands as well as several spectral lines. Furthermore, we apply both zero and one dimensional multi-threaded hydrodynamic loop models to synthesize light curves and spectra for each flare. Funding provided by NSF REU solar physics program at CfA, grant number ATM-0851866 and Marlboro College.
