• This change requires a documentation update

How Has This Been Tested?

import datetime as dt
import matplotlib.pyplot as plt
import pysat
import pysatNASA

# Initalize the instrument, download and load the data.  Loading will bring up logger warnings from the pysat function
# that aren't important in this instance
ssusi = pysat.Instrument(inst_module=pysatNASA.instruments.dmsp_ssusi, tag='edr-aurora', inst_id='f17')
ssusi.download(start=dt.datetime(2015, 1, 1))
ssusi.load(date=dt.datetime(2015, 1, 1))

# Create a plot like the one shown here
fig = plt.figure()
axs = fig.add_subplot(212, projection='polar')
axn = fig.add_subplot(211, projection='polar')
dvar = 'SOUTH_POLAR_GEOGRAPHIC_LONGITUDE'
lvar = 'SOUTH_POLAR_GEOGRAPHIC_LATITUDE'
ndvar = 'NORTH_POLAR_GEOGRAPHIC_LONGITUDE'
nlvar = 'NORTH_POLAR_GEOGRAPHIC_LATITUDE'

# Replace colors and markers with a list of colors and markers
for i, dtime in enumerate(ssusi.index):
    axs.plot(np.radians(ssusi[dvar][i]), 90 + ssusi[lvar][i], '.', label='{:}'.format(dtime), color='k')
    axn.plot(np.radians(ssusi[ndvar][i]), 90 - ssusi[nlvar][i], '.', color='k')

# Do various formatting to make things look nice

The warning is what I couldn't get rid of. The error you're getting is from a mistake in the sample code (now fixed). I addressed the extra space concern.
