No Detection of a Scar on Jupiter in the NIR

Some news about the Jupiter flash which was detected on September 10. I reported the absence of detection in the visible light from data collected by amateur astronomers. Glenn Orton, a  colleague from the Jet Propulsion Laboratory,  sent me yesterday two observations of Jupiter taking with the IRTF telescope and the SpeX Guiding camera in the near-infrared. No scar, or debris field, can be seen at the location of the flash. The meteoroid did not enter in the inner part of the planet atmosphere. This observation confirms that it was most likely a meteor.
