  We observe damped temporal oscillations in the scale factor at a dominant
frequency of ~ 7 cycles/Hubble-time in the Pantheon Compilation of 1048 type Ia
supernovae (SNe). The residual oscillations observed in the Pantheon data
closely matches and reaffirms our initial observation of oscillations from
earlier SNe data (primarily SNLS3, 2011) at 2-sigma confidence. The nearly
identical shapes in amplitude, frequency, phase and damping constant makes it
highly likely the signal is real. Furthermore, 2/3 of the Pantheon SNe cover
different portions of the sky compared with SNLS3 strengthening this
conclusion. Our model describing the oscillation, presented in an earlier
paper, is a simple scalar field harmonic oscillator coupled to the LCDM
Friedmann eqn, but carried into the present epoch. The scalar field energy
density plays the role of the dark matter energy density in LCDM cosmology,
fits well as an average, and closely matches the present dark matter density
parameter, suggesting the oscillation play a role in the dark matter sector.
Temporal oscillations in the scale factor and its derivative, as described in
the present work, would also induce temporal oscillations of the Hubble
parameter.
