Description:
The relation between the Ultra Compact Objects (hereafter UCOs)
recently discovered in the Fornax cluster (Drinkwater et al.,
2000PASA...17..227D; Hilker et al., 1999, Cat. <J/A+AS/134/75>) and
the brightest globular clusters associated with the central galaxy
NGC 1399 has been investigated. A spectroscopic survey on compact
objects in the central region of the Fornax cluster was carried out
with the 2.5 m du Pont telescope (LCO) at Las Campanas, in the three
nights of 2000/12/30 to 2001/01/01. The magnitude limit was approx.
V=21 mag, the spectral resolution approx. 4{AA}. UCOs and the bright
NGC 1399 globular clusters with similar brightness were inspected. 12
GCs from the bright end of the globular cluster luminosity function
have been identified as Fornax members. Eight are new members, four
were known as members from before.

Note (1): *: The object's radial velocity could be determined only by
identification of emission lines, because cross correlation
yielded unreliable results.
Note (2): The photometry is from Hilker et al. (2002, in prep.)
Note (3): Type of objects:
GCC: Globular cluster candidate
UCO: Ultra Compact Object (Drinkwater et al., 2000PASA...17..227D,
