The solar burst of 2006 December 06 reached a radio flux density of more than
1 million solar flux units (1 sfu = $10^{-22}$ W/m$^2$/Hz), as much as 10 times
the previous record, and caused widespread loss of satellite tracking by GPS
receivers. The event was well observed by NJITs Owens Valley Solar Array
(OVSA). This work concentrates on an accurate determination of the flux density
(made difficult due to the receiver systems being driving into non-linearity),
and discuss the physical conditions on the Sun that gave rise to this unusual
event. At least two other radio outbursts occurred in the same region (on 2006
December 13 and 14) that had significant, but smaller effects on GPS. We
discuss the differences among these three events, and consider the implications
of these events for the upcoming solar cycle.
