2006年12月太阳耀斑极端射电通量密度的成因和程度

Cause and Extent of the Extreme Radio Flux Density Reached by the Solar Flare of 2006 December 06

Dale E. Gary

摘要:

2006年12月6日的太阳爆发达到了超过100万太阳通量单位(1 sfu = $10^{-22}$ W/m $^2$ /Hz)的无线电通量密度,是以前记录的10倍,并导致GPS接收器的卫星跟踪广泛丢失。NJIT的欧文斯谷太阳能阵列(OVSA)对这一事件进行了很好的观察。这项工作集中在准确确定的通量密度(由于接收器系统被驱动到非线性变得困难),并讨论了太阳上的物理条件,引起了这一不寻常的事件。在同一地区至少发生了另外两次射电爆发(2006年12月13日和14日),对GPS产生了重大但较小的影响。我们讨论这三个事件之间的差异,并考虑这些事件对即将到来的太阳活动周期的影响。

英文摘要:

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.
