VLA A configuration images of Betelgeuse at 0.7 cm at three different epochs. These images have been created by naturally weighting the visibilities and applying a restoring beam corresponding to the size obtained from uniform weighting. The restoring beam is located in the bottom left corner of each panel while the red circle is the approximate location and size of the optical photosphere. The contour levels are plotted at 10%,20%,...,90%, and 99% of the peak flux density. From left to right the beam sizes are 40′′ × 40′′, 45′′ × 41′′, and 48′′ × 40′′. Left panel: the L+98 image shows an asymmetry to the east of the photosphere which is here assumed to be coincident with the intensity-weighted centre of the radio disk. A photospheric angular diameter of 45 mas (Dyck et al. 1996) was assumed by the authors. Middle and right panels: our images show no large scale asymmetries. The position of the photosphere is here assumed to be located at the peak of the emission and we adopt the photospheric angular diameter of 42.49 mas (Ohnaka et al. 2011).
