Comet C/2010 X1 ( Elenin) may be studied with the help of one of the biggest radio telescopes in the world – Arecibo. This only very recently became known. Lance Benner answered my letter having to do with the detection of NEOs with the help of the 70 meter Goldstone radio telescope. From his words we learn that finding a comet at a distance of 0.23 a.u. is a complex task for their radio telescope. For that purpose the gigantic 300 meter Arecibo radio telescope is better suited.

According to Ellen Howell, such work has been done at Arecibo and in 30-50% of the cases it has been successful. An application for four nights of observing time in the period from September 27 to November 10, 2011 has already been sent to the committee that apportions observing time. I hope these observations will all take place and that they will be successful!
