   Many of us have learned the asterism shape for Leo the Lion as a backward question mark. Or if you are from a somewhat bygone era you may have learned Leo’s shape as a scythe, like the one a farmer harvesting wheat would have used ‘way back whenever’. However the problem, at least to me, has always been in using the bright star Regulus as the ‘dot’ for the backward question mark shape. Tonight that problem is resolved by the position of the waning gibbous Moon. For a while the Moon will be the dot, albeit a large and bright one, directly below Regulus as the graphics show. Both of which are set for 9:30 pm CST, or 3:30 UT on the 19th. However the Moon and the Earth keep on moving so between the time these graphics were set for and the same time tomorrow the Moon will have moved eastward past Regulus.

Caution: Objects viewed with an optical aid are further than they appear.
