AB: We find a clear relationship between the daytime foF2 at the equator and solar X-ray fluxes during 1998-2000. The digisonde measurements of foF2 are from Jicamarca, Peru; and are compared with the solar soft X-ray fluxes from the Student Nitric Oxide Explorer (SNOE) satellite. The X-ray fluxes measurements are in wavelength bands of 2-7nm, 6-17nm and 19-21nm. After removal of trends with periods longer than 27 days, comparison of individual digisonde measurements shows a correlation of approximately 0.4 with the solar fluxes; and the effects of the sun's rotation can clearly be seen. Previous analysis of averaged Total Electron Content (TEC) from Ancon, Peru, found a correlation of 0.6, with the X-ray fluxes leading TEC approximately 1.3 days.
