ResumoBose-Einstein condensation of sodium atoms has been observed in a novel ``cloverleaf'' trap. This trap combines tight confinement with excellent optical access, using only dc electromagnets. Evaporative cooling in this trap produced condensates of $5\ifmmode\times\else\texttimes\fi{}{10}^{6}$ atoms, a tenfold improvement over previous results. We measured the condensate fraction and the repulsive mean-field energy, finding agreement with theoretical predictions.
