Variations in the axisymmetric transport of magnetic elements on the Sun: 1996-2010
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
We measure the axisymmetric transport of magnetic flux on the Sun by cross-correlating narrow strips of data from line-of-sight magnetograms obtained at a 96-minute cadence by the MDI instrument on th...

Interplanetary Shock Parameters during Solar Activity Maximum (2000) and Minimum (1995-1996)
Interplanetary Shock Parameters Solar Activity Maximum
2010/10/27
Interplanetary shock parameters are analyzed for solar maximum (year 2000) and solar minimum (years 1995-1996) activity. Fast forward shocks are the most usual type of shock observed in the interplane...
