论文摘要
2022年2月3日，在〜1613 UT上，SpaceX从佛罗里达州肯尼迪角（Cape Kennedy）推出了49颗星条卫星，进入了约210公里的海拔轨道，他们将接收随后的提升。我们假设有9个卫星得到了随后的提升，并成功获得了稳定的轨道。 2月7日清晨，几个星条卫星重新进入了气氛。两次磁性风暴发生在2月3日的〜1056 UT，峰值-H强度为-80 nt的峰值峰值强度，第二秒为2月4日，Sym -H峰强度为-71 nt。 ESA极轨道群B卫星数据表明，在〜500 km的高度下，数天赤道和中纬度的风暴时间空气质量密度增强，密度峰值高约50％，高约50％。与安静的夜间值相比，夜间密度峰值的增加约为100-190％。迅速穿透电场引起了日期的F-Region O+离子的升高，并且夜间O+离子的向下对流可以解释磁性风暴主相期间的群B昼夜不对称，这可能是造成Starlink卫星损失的原因。我们40个星际链接卫星损失的情况与Dang等人不同。 （2022）假设星条林的卫星在210公里的高度没有得到任何提升。
On ~1613 UT, 3 February 2022 SpaceX launched 49 Starlink satellites from Cape Kennedy, Florida into ~210 km altitude orbits where they were to receive subsequent boosts. We assume that 9 satellites received subsequent boosts and succeeded in obtaining stable orbits. Several of the Starlink satellites reentered the atmosphere in the early morning hours of 7 February. Two magnetic storms occurred one with a peak SYM-H intensity of -80 nT at ~1056 UT on 3 February and a second with a SYM-H peak intensity of -71 nT on ~2059 UT 4 February. The ESA polar orbiting Swarm B satellite data show that enhanced storm-time air mass densities occurred in dayside equatorial and midlatitudes at ~500 km altitude with a density peak increase of ~50% higher than quiet time daytime values. The nightside density peak increase was ~100-190% compared to quiet time nighttime values. Prompt penetration electric fields causing ExB uplift of the dayside F-region O+ ions and the downward convection of the nightside O+ ions can explain the Swarm B day-night asymmetry during the magnetic storm main phases and are the probable cause of the losses of the Starlink satellites. Our scenario for the 40 Starlink satellite losses is different from Dang et al. (2022) who assumed that the Starlink satellites received no boosts at 210 km altitude.
