VLT search for the infrared counterpart of IE 1740.7-2942

We report the results of our search for the near infrared counterpart of the microquasar IE 1740.7-2942 using the VLT1. For the first time, several counterpart candidates have been found in our Ks-band images that may be consistent with the best radio and X-ray positions available for IE 1740.7-2942...
