report on behalf of a larger collaboration:
We have observed the field of GRB 120514A (Mangano et al.
GCNC 13289) using LABOCA/APEX at Chajnantor (Chile) in the
870 micrometer band. The weather conditions were good, with
precipitable water vapour at the time of the observation of ~0.5mm.
Observations began on May 14 at 4:55 UT (3.7 hr after the burst)
and were performed using the photometric mode, centred at the
enhanced X-ray position (Evans et al. GCNC 13292).
On a preliminary analysis of 160 min on source, we detect a flux
density at the position of the afterglow of 6.2+/-2.3 mJy.
Further observations are foreseen. We encourage follow-up
observations in other wavelengths.
