Slide 7 7 Mid-continent Magnetoseismic Chain (McMAC) ● Field line resonance method requires close separation between ground stations in the north-south direction. ● The mean north-south separation between two adjacent McMAC stations is 275 Km. ● Joint operation with CANOPUS Churchill Line (Canada), IGPP-LANL (U.S.) and MAGDAS (Japan) provides the magnetic field data from L = 1.3 to 11+ at one local time (note: the widest stretch of magnetic latitude on the earth). Pi: Peter Chi

Slide 8 8 McMAC Sites Lyford, TX (Lyford High School) Linares, Mexico (Universidad Autónoma de Nuevo León) Glyndon, MN (Minnesota State U. Moorehead) Bennington, NE (U. of Nebraska, Omaha) Richardson, TX (U. of Texas, Dallas) San Antonio, TX (SwRI) Worthington, MN (Minnesota West College) Americus, KS (Emporia State U.) Purcell, OK (U. of Oklahoma) (All nine stations installed)

Slide 9 9 ULF Activity Observed by McMAC, CARISMA, IGPP-LANL Combined 1-day2-hourLT = UT – 6.37 (hr)

Slide An Example of McMAC Measurements: FLR Frequency & Equatorial Density UT Model-predicted plasmapause L (or Lpp) well agrees with FLR- inferred results. The low Lpp can be explained by the Kp value of 5+ earlier in the day Lpp (model)

Slide McMAC Data Availability (as of 5/16/07)

Slide McMAC Data Dissemination McMAC Web Site: ( Project information McMAC data files Density estimation (in preparation) NASA VMO (UCLA Hub – PI: Ray Walker) To provide access to all McMAC data Important in retrieving other space physics data for the same time intervals Contact Peter Chi for details.
