Solar flares localized explosive release of energy; appear as a sudden short-lived brightenings in solar luminosity. Solar flares and mores specifically the larger class flares,the GOES M-Class (peak flux
greater than 10-2 erg cm-2 s-1 ) and GOES X-Class flare (peak flux greater than 10-1 erg cm-2 s-1 ) contribute to space weather effects such as radio wave disturbances, atmospheric drag on satellites,
astronaut safety , and ionosphere currents. This research examines the luminosity in flares in the X-rays using Hinode's XRT and in the extreme ultraviolet using STEREO data to gain an understanding as to
the energy budget of the flare. Hinode's XRT data was utilized to classify a flare's class, luminosity. Using the work of Scwhadron et al (2006) and Korreck et al. (2008) we compared this luminosity to the
power of the solar wind. The x-ray observations taken with Hinode more closely track the power of the solar wind at 1AU than that of the EUV observations of the STEREO. This is an important step to
understanding the energy of the flare as well as the future of space weather prediction. This research lays groundwork for comparing XRT x-ray intensity of flares with those of the SDO- AIA instrument. This
work was supported by the NSF-REU program.
