There was a quiescent stage from late 1963 to mid-1964, and it was followed by a renewal of seismic activities before the main shock.

G 0 phase is viewed as either an extended G 1 phase where the cell is neither dividing nor preparing to divide and or as a distinct quiescent stage which occurs outside of the cell cycle.
3.
Temperature estimates for the star range from around 18, 000K to well over 30, 000K . The hotter temperatures found from fitting the spectral energy distribution ( SED ) are consistent with the calculated luminosity of an LBV in the quiescent stage, but the spectrum is that of a cooler star.
