# spacepy.irbempy.find_magequator

spacepy.irbempy.find_magequator(ticks, loci, extMag='T01STORM', options=[1, 0, 0, 0, 0], omnivals=None)

  call find_magequator from irbem library and return a dictionary with values for Bmin and the GEO (cartesian) coordinates of the magnetic equator

  Parameters:
    - ticks (Ticktock class)containing time information
    - loci (Coords class)containing spatial information
    - extMag (string)optional; will choose the external magnetic field model

      possible values [‘0’, ‘MEAD’, ‘T87SHORT’, ‘T87LONG’, ‘T89’, ‘OPQUIET’, ‘OPDYN’, ‘T96’, ‘OSTA’, ‘T01QUIET’, ‘T01STORM’, ‘T05’, ‘ALEX’, ‘TS07’]

    - options (optional list or array of integers length=5)explained in Lstar
    - omni values as dictionary (optional)if not provided, will use lookup table
    - (see Lstar documentation for further explanation)
  Returns:
    - results (dictionary)containing keys: Bmin, Coords instance with GEO coordinates of

      the magnetic equator
