  2. 紫金山天文台太阳射电频谱仪 宁宗军 工作波段:4.5-7.5 京赫兹 时间分辨率:5 毫秒 工作带宽:10 兆赫兹 开始工作:1998年 数据积累:100多个耀斑 科学目标:太阳耀斑中时间精细结构 科学成果:发表论文10多篇(SCI)

  3. 观测例子1: 2000年3月24日太阳耀斑 动态频谱 射电谱 时变流量曲线

  4. GOES 卫星 观测例子2: 2003-3-18太阳耀斑 RHESSI卫星 紫台频谱仪观测到该耀斑中的精细结构—脉动飘逸结构(耀斑加速区波动加速的辐射特征) Ning et al. 2007 Nobeyama PMO频谱仪 PMO频谱仪

  5. 总结 紫金山天文台4.5-7.5GHz太阳射电频谱仪: 耀斑中的时间精细结构(理解耀斑中加速过程以及波动传播)---973日地关系的起源

  6. 科学产出 观测已近积累有上百个耀斑。 发表论文SCI10篇:(以紫台资料为主) Xu et al. 2000(ChPhL,17,460) 2001(CHJAA,1,469) 2003(SoPH,216,273) 2004(A&A,425,281) 2005(ChPhL,22,3229) Ning et al. 2003(CjA&A,3,381) 2005(A&A,437,691); 2007(SoPH,241,77); 2007(SoPH,241,101); 2008(SoPH,250,107)

  7. EIS SOT XRT HINODE • HINODE (which was called SOLAR-B before launch) was successfully launched on 23 Sep, 2006. Observations started from the beginning of Nov 2006. 宁宗军

  8. Solar-B Fields of View N EIS (360”x512”) E W SOT:BFI (205”x102”) SOT:NFI/SP (328”x164”) XRT (2048”x2048”) S SOHO/EIT FeXII 195A

  9. scientific targetsOrigin of Solar Magnetic Activities XRT EIS • Active phenomena observed in the solar atmosphere are strongly coupled with magnetic fields. • Causal linkages between evolution of elementary magnetic fields and the active phenomena are investigated. • Size of elementary magnetic fields: 0.2-0.3 arcsec (150-220 km) Corona Chromosphere The Sun Temperature minimum SOT Photosphere Photospheric magnetic field (White/Black: N/S polarity)

  10. Solar Atmosphere Corona Transition Region XRT Corona EIS Temperature (K) TR/Corona (EUV) 光球 SOT Chromosphere Photosphere Height from Photosphere (km)

  11. SOT: First Press Release Image Solar photosphere seen at 430 nm. Small bright points between granules are clearly seen. 104 km

  15. 太阳耀斑2007-12-14 At the same time: 1. Blue shift for the hot coronal lines 2. Both energy- and time- dependence distributions seen at HXR (~320km/s) Ning & Cao 2011

  16. 总结 Hinode 的观测: 宁静区,活动区,极区,边缘 耀斑,日冕物质抛射(暗条爆发) 对日地关系有密切关系! --973日地关系的源头!

  17. SOT的科学目标 • 精确测量光球矢量磁场 • 与磁场相关的光球和色球的动态特征 • The combined SOT system is optimized for accurate measurement of the vextor magnetic field in the photosphere and dynamics of both the photosphere and chromosphere associated with the magnetic field.

  18. XRT的科学目标 • 光球磁场产生、传输、浮现 • 耀斑重磁场能量的扩散 • 日冕加热 • 日冕物质抛射

  19. EIS—EUV Image Spectrometer • Transition region • Corona • Solar flare • 170-210 Å and 250-290 Å • two narrow slits (1" & 2" width) and two wide slots (40" & 266" width)
