This radar image of 2007 TU24 was obtained on January 28, 2008, about 12 hours before the asteroid's 1.4-lunar-distance pass by the Earth, from an observation that used the Arecibo telescope to transmit a 300-kilowatt beam of radio energy toward the asteroid and the Robert C. Byrd Green Bank Telescope, (GBT) in West Virginia to receive the echoes. The image summed echoes recorded over about three minutes. The intrinsic resolution of the image is about eight meters (25 feet). ...

... ST-ECF, ESO, STScI and the NICMOS IDT organized a workshop on near infrared imaging from space and ground was held in Pula on May 26-27, 1998. ... The meeting was held in May 1998, about one year after science observations started with NICMOS, and about half a year before the Infrared Spectrometer and Array Camera (ISAAC) starts to operate on the VLT. Currently, it is expected that NICMOS will operate until the end of 1998. ...
