Immler) detected the high-mass X-ray binary candidate RX J0520.5-6932 in a moderately bright X-ray outburst. Assuming a power-law spectrum with a photon index of 0.9 and absorption of 10&lt;SUP&gt;21&lt;/SUP&gt; cm&lt;SUP&gt;-2&lt;/SUP&gt;, we derive a 0.2-12 keV flux of 1.67 × 10&lt;SUP&gt;-12&lt;/SUP&gt; erg s&lt;SUP&gt;-1&lt;/SUP&gt; cm&lt;SUP&gt;-2&lt;/SUP&gt;. This flux is ~25 times higher than measured during a recent XMM-Newton observation (see below).</style></abstract></record></records></xml>
