May 2011 TLO is available

Tony Cook, TLP coordinator, has requested observational support to re-observe the site of a TLP under similar illumination conditions.  Obviously, the time of observation is critical (although I would guess that series of observations spanning the requested time could also be interesting).   The information that Tony provided is below, including the relevant time (On the web link, look for April 15 …. Aristarchus observed by Greenacre on 1963-11-28).  Anyone that can obtain images please send them to both Tony at atc@aber.ac.uk and me at wayne.bailey@alpo-astronomy.org

On Apr 15 at UT 02:53-06:28 or somewhere within these time limits, depending upon where you are in the States, the illumination + topocentric libration will be the same as it was for the 2nd of the Greenacre TLP in Aristarchus seen on 1963 Nov 28.

Jay Albert and Bob O’Connell plan to observe to get some calibration sketches and images to compare with material that Bob has managed to find on the original observation.

It would be great, in order to maximize chances, if others in North America could take a look and try to obtain some high resolution images (monochrome or colour) to act as a comparison. Full details of the original TLP report and observing times are given on:

http://users.aber.ac.uk/atc/tlp/tlp.htm

for each of the states in the USA and Canada.

I guess what we are trying to do is to see if the event could have been caused by atmospheric spectral dispersion, natural surface colour etc. We’ve tried this before, but higher resolution images would certinly help nail this once and for all.
