Comet C/2007 K5 (Lovejoy) 26 May 2007 discovery 
images by/Copyright Terry Lovejoy

Terry Lovejoy in Queensland, Australia has posted a gallery for comet C/2007 K5 (Lovejoy) with his discovery images. The illustration here shows part of the first 2007 May 26.340 image at full resolution (7.6"/pixel) with the comet at center, and, above that, a mosaic at 33.3% size made from the first image (comet to the right) and an image from May 28.347. North is up and east is left. This observing was done with Canon digital cameras using 200mm lenses. Copyright Terry Lovejoy, used with permission. Further astrometry has been published today (see below), and read more about this comet in June 2nd news.


Contents  on 8 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.

For a list of all risk-rated objects recently in view, see our ephemerides page.

An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from an orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" for more about all this.
