我们报告了从2001年开始，美国宇航局IMAGE航天器上的低能中性原子（LENA）成像仪对太阳风中性分量的观测。中性太阳风存在明显的年调制，上游区域外的通量被用来确定尘埃几何截面在向阳方向上的上限，即1天文单位处的Γ1AU < 6×10−19 cm−1。这个值与黄道光的推论一致。
We report observations of the neutral component of the solar wind from the Low Energy Neutral Atom (LENA) imager on the NASA IMAGE spacecraft from year 2001. There is a pronounced annual modulation of the neutral solar wind, and the flux outside of the upstream region is used to place an upper limit on the dust geometric cross section in the sunward direction at 1 AU of Γ1AU < 6×10−19 cm−1. This value agrees with inferences made from the zodiacal light.
