Detail of B − V and Tycho photometry observations showing “saw-tooth” variations with an amplitude of  ≈0.2 m, and a sequence time of a few hundred days. The difference between the Tycho and B − V mean values is due to differential pass-band reddening; the Tycho data points have been obtained at small time differences and may indicate a field of shockwaves.
