Solar Flux Index (SFI) surpassed 100!Monday Feb 14, 2011
For the first time – since Dec 12, 2006 – the Solar Flux Index @2800 MHz reached and surpassed 100 sfu. The three-digit number index is also a record for solar cycle 24!
The following plot shows daily Solar Flux since 2006 and the wide time-window (more than 1500 days) between last two “over 100 sfu” measurements.
Post Scriptum: 107 sfu in the plot refers to the 2000 Penticton measurement
