Individual acoustic rays generated at the depth of 45 km in the interior and travelling to the bottom of the plot by a moving supersonic source with a velocity of v = 150 km s−1, depositing a momentum below the photosphere under a +30° angle from the local vertical for the times after the shock deposition shown above the plots. We note that Z is the depth in the solar interior, the photosphere is denoted by Z = 0, and the X-axis denotes a distance on the surface in Mm from the point of the momentum deposition. The mustard arrow shows the direction of the wave propagation. The points of ray reflection from the photosphere seen in the top left corner 8:50 min after the shock deposition are observed as ripples on the surface, or a sunquake, which are propagating from the central point of the momentum deposition in the flaring event outwards to all the directions.
