Look for the Red Planet rising in the east at sunset, shining brighter than a 1st-magntitude star. Alan Dyer sends this picture of the Red Planet from Coonabarabran, NSW, Australia:
"The reddish tint of Mars contrasts nicely with blue-white Spica, the brightest star in Virgo," says Dyer. "If the arrangement of Mars and Spica looks unusual, it's because I took this from Australia. So the relative position of Mars and Spica looks upside down compared to a northern hemisphere view. The gum trees in the foreground are illuminated by the waxing Moon."
