---------------------- Flag this message [LSA-ALPO] Observation Request Wednesday, April 13, 2011 10:19 AM From: "Lunar Section" <Larry@CEastronomy.org> Add sender to Contacts To: LSA-ALPO@yahoogroups.com 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 ====================================================================== BAA electronic bulletin ====================================================================== Lunar images needed of Aristarchus/Herodotus on 2011 Apr 15 This Friday, April 15, between 19:00 and 21:00 UT, the Aristarchus and Herodotus area of the Moon will match the same illumination, to within +/- 0.5 degrees, as that observed during the famous Transient Lunar Phenomena (TLP) seen by Greenacre & Barr from Flagstaff Observatory back on 1963 Oct 30. The BAA Lunar Section would welcome any high resolution monochrome, or especially colour, images of this area during this time period. Such observations would be very helpful so that the Lunar Section can test out the 'atmospheric spectral dispersion' theory, proposed by Sheehan & Dobbins (Sky & Telescope, 1999), or to see if natural surface colour could explain some of the colours seen back in 1963. Observations should be emailed to the Lunar Section Assistant Director Dr Tony Cook at: tlp@baalunarsection.org.uk If you are interested in trying to resolve other past historical lunar mysteries, by observing under the same illumination conditions, then these can be found listed for different geographical sites across the world at http://users.aber.ac.uk/atc/tlp/tlp.htm They are suitable for both visual and imaging-capable observers.
