  We present the analysis of a compact flare that occurred on 2002/02/26 at
10:26 UT, seen by both RHESSI and TRACE. The size of the nearly circular hard
X-ray source is determined to be 4.7(+-1.5)" from the modulation profiles of
the RHESSI collimators. The power-law distribution of non-thermal photons is
observed to extend down to 10 keV without flattening, and to soften with
increasing distance from the flare kernel. The former indicates that the energy
of the precipitating flare electron population is larger than previously
estimated: it amounts to 2.6(+-0.8)10^30 erg above 10 keV, assuming
thick-target emission. The thermal energy content of the soft X-ray source
(isothermal temperature of 20.8(+-0.9)MK) and its radiated power were derived
from the thermal emission at low energies. TRACE has observed a low-temperature
ejection in the form of a constricted bubble, which is interpreted as a
reconnection jet. Its initial energy of motion is estimated. Using data from
both satellites, an energy budget for this flare is derived. The kinetic energy
of the jet bulk motion and the thermal and radiated energies of the flare
kernel were more than an order of magnitude smaller than the derived electron
beam energy. A movie is available on the CD-ROM accompanying this volume.
