No Detection of a Scar on Jupiter in the NIR

[ 3 ] Comments

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.

Over the past 15 years, he has dedicated his research to the study of our solar system using mainly ground-based telescopes equipped with adaptive optics. More recently he has been also involved in the definition of new generation of AOs for 8 -10 m class telescopes and future Extremely Large Telescopes. He has developed algorithms to process and enhance the quality of images, both astronomical and biological, using fluorescence microscopy. His currently involved in the development of the Gemini Planet Imager, an extreme AO system for the Gemini South telescope which will be capable of imaging and record spectra of exoplanets orbiting around nearby stars.

    J’ai lu rapidement dans le “Ciel et Espace” de septembre un article qui mentionnait le lancement d’un téléscope spatial en IR pour surveiller les météorites. Il est appelé “sentinelle de la Terre”. Ce serait en 2017, le mâitre d’ouvrage étant la fondation américaine à fonds privés B612. C’est vrai ?
