Asteroid timing accuracy

[Dr Paul Leyland]

T Marshall Eubanks tweeted this a few minutes ago and I suggest that should be of interest to BAA observers.

The second International Asteroid Warning Network (IAWN) Timing Campaign will check the accuracy of observation times reported by observers of near-Earth asteroid 2005 LW3 on Nov. 23th / 24th, 2022, when it will be as close as 3 lunar distances to Earth.

I will give it a go if I am back in Tacande on that date. Note that it should be a decent altitude after dark at the longitude of western Europe and the Canaries on 24th November. For me it will at the zenith at 20221124T2230 and predicted to be V=13.7

Paul, the link appears to be missing a 3 at the end. I believe this is the correct format https://iawn.net/obscamp/2005LW3

My apologies. A cut & paste error which I failed to spot. Thanks for posting the correction.

You don’t need to wait for a fast moving NEO to pass by. I regularly check my timing accuracy by doing astrometry of GPS satellites as explained by Bill Gray here:
