  We have compiled a catalog of solar flares as observed by the Extreme
ultraviolet Imaging Telescope (EIT) aboard the Solar and Heliospheric
Observatory (SOHO) spacecraft and the GOES spacecraft over a span from 1997 to
2010. During mid-1998, the cadence of EIT images was revised from two images
per day to 12 minutes. However, the low temporal resolution causes significant
data gaps in capturing much of the flaring phenomenon. Therefore, we monitor
possible errors in flare detection by flare parameters such as temporal
overlap, observational wavelength, and considering full field of view (FOV)
images. We consider the GOES flare catalog as the primary source. We describe
the technique used to enhance the GOES detected flares using the Extreme
Ultraviolet (EUV) image captured by the EIT instrument. In order to detect
brightenings, we subtract the images with a maximum cadence of 25 minutes. We
have downloaded and analyzed the EIT data via the Virtual Solar Observatory
(VSO). This flare dataset from the SOHO/EIT period proves indispensable to the
process of the solar flare predictions as the instrument has covered most of
Solar Cycle 23.
