6R10DB9 on March 20th 
© 2007 Great Shefford Obs.

Peter Birtwhistle says he is "quite looking forward to mid-June when 6R10DB9 comes rushing through one last time." He caught it before, as seen in this imagery from March 20th. "It" is believed to be a tiny asteroid that has been a temporary satellite of the Earth. See Friday's report about the radar observations planned for its passage at 0.7 lunar distance this month on the way back into heliocentric orbit.
      About this image: It comes from a composite of 176 six-second exposures made over a period of 17 minutes and 36 seconds. The object was moving at 24"/min. in PA 357° (upward) at magnitude R=19.3 and fading. The inset has the pixels doubled to twice size. ©Copyright 2007 Great Shefford Observatory, where you will find more info.


Contents  on 3 June '07

WELCOME to A/CC's prototype daily news publication designed to be the viewing end of a planned autonomous 24-hour news service. The new tools and this publication format are working well enough now to share with readers. It is expected that this approach will require less time to maintain than our previous news and small asteroid pages, which were retired on May 14th. There's still more development ahead and there probably will be some glitches along the way, but this is what's needed to keep up with the increasing pace of minor-object news. The CRT page will be maintained separately for a little while longer, until all of this is working smoothly. And the CRT and small-asteroid ephemerides will be kept going.
