LIGHT AREA 6: seen in Wr47 is very similar to the bright spot seen on 19 November. The present one, however, was contained within a larger bright area and just stood out as more intense than the surroundings.
SIZE and SHAPE: seemed a tiny bit bigger than the 19 Nov spot. About the same size as the spc. Once again, a striking circular shape.
COLOUR: A bright violet in Wr47. In fact the spot was seen in at least one more filter (either Wr58, 15 or 80A), but I forgot to take notes. Cloud or haze or frost over Ascraeus Mons.
