The authors report on low-field measurements of the Meissner effect in a BYCO high-{Tc} superconductor with large pinning. The positive Meissner effect (PME) observed at low fields in a SQUID magnetometer is shown to be an artifact arising from the presence of a small field gradient. No PME is observed using an extraction technique to measure the magnetization.
