Solar Flare Event.<br />

The following is an event I recorded on 432 MHz during 28 th <strong>and</strong> 29 th October 2003.<br />

It was interesting to note that the IPS did not give a confirmed IFLUX value<br />

(estimated 235 sfu) on this date.<br />

From my recordings I estimated that the sfu actually peaked well in excess of 500 sfu.<br />

It is my belief that there appears to be some degree of uncertainty of values in excess<br />

of IFLUX values of 250 sfu.<br />
