    Initially pulled the information from Omar's site, but delta's declination
    was 0.1' off, and zeta later proved to way off (Omar listed declination as
    0d 00.4' N!).
    Looked at the spreadsheet after a nights rest and found a blunder in
    entering delta dec.  We now agree at 2d 44.2' before refraction correction
    (2d 44.1' with correction.)
    Values currently used:
                SHA          Dec
    Delta       276  55.3    0  17.6 S
    Zeta        274  44.1    1  56.3 S
    Started looking for a pair for the summer.
    Despite the S declination, Beta and delta Scorpii (approx. SHA 119) look
    good within an hour or two of meridian passage (about 3 am for us now--but
    getting within bed time in couple of months).
