Hi Mark,

I'd suggest Acamar -- Theta Eridani

Acamar Theta Eri SAO 216113 HD 18622
RA: 02h 58m 15.720s Dec: -40° 18' 17.00"
Mag(v): 3.22 B-V: +0.156 Spect: A4III+... Alt: -15.8°, Az: 181.6°


PZ 2 RA: 02h 58m 15.7s Dec: -40° 18' 17"
Components: --- Mags: 2.9 / 4.0 Spect: A4III A1V # Obs: 60
Obs Dates: 1835 / 1997 Sep: 8.3 / 8.3 p.a.: 82 / 90

Which should be at about 30 degrees elevation at about 8pm EDST. Is the brightest star in its locale so easy to find approx 1/3 of the way from Achernar (Alpha Eri) to Rigel (Beta Ori).

A little later on, perhaps Gamma Arietis?

STF 180
RA: 01h 53m 31.8s Dec: +19° 17' 39"
Mags: 3.9 / 3.9 Spect: A1pSi B9V # Obs: 99
Obs Dates: 1821 / 1994 Sep: 8.6 / 7.8 p.a.: 358 / 1


Best,
