Mercury & Painted Ladies
The Planet Mercury appears as a somewhat conspicuous "star" in the west at dusk on Saturday, April 3, but nowhere near as bright as Venus, which lies only three degrees to Mercury's left. For the next week or so, Mercury will be enjoying its best evening-sky apparition of the year.
Painted Lady Butterflies may be on the wing across San Diego County this month on what could be a significant migration from the Anza-Borrego Desert and northern Baja California toward the coast. Chances are you will see them winging west or northwest, toward greener, more succulent vegetation and away from the drying desert flora.
