                         Surveyor (MGS) we report X-ray flare responses in the E region 
                         ionosphere of Mars during six events that occurred on 28 March and 
                         6 April 2001, 17 and 18 March and 21 April 2003, and 19 February 
                         2005. We have developed a time-dependent Analytical Yield Spectrum 
                         model to calculate a time series of photoionization rate, 
                         photoelectron impact ionization rate, photoelectron flux, ion 
                         density, electron density, and ionospheric electron content (IEC) 
                         of the E region for each flare day. The estimated production rate, 
                         flux, and densities increase by 1-2 orders of magnitude due to 
                         effect of these flares in the E region ionosphere of Mars. The 
                         estimated IEC are compared with the measured IEC. It is found that 
                         the normalized IEC of the simulated E layer increased by a factor 
                         of 5-10 at the flare time compared to a factor of 2 enhancements 
                         in the normalized IEC of the corresponding MGS profiles.",
