     On 1964 Jun 29 at UT 07:05-07:33 Bartlett (Baltimore, MD, USA, 
     4" reflector x240, S=5, T=4) suspected a violet glare? on the 
     EWBS of Aristarchus, but was too faint to be certain. The bright 
     art of the floor was granulated and had a ceppery tint. The 
     Cameron 1978 catalog ID=827 and weight=4. The ALPO/BAA weight=2.

     On 1958 Nov 01 at UT 00:00 a TLP was seen on the Moon (location and 
     observer not given). The Reference for this is Palm, 1967. The Cameron

     On 1980 Aug 30? at UT 08:00? D. Louderback (South bend, WA, USA, 8" 
     refletor x140) found the north wall to be very bright in red light 
     (this is not normal as it is usually bright in blue - according to 
     Cameron). The brightness was 9.7 (red) and 9 (blue no filter)compared 
     to Eimmart's 8.7. Louderback thought that they observed an oranfe-
     yellow tinge. Cameron 2006 catalog ID=108 and weight=3.

2018-Aug-27 UT 03:58-07:43 Ill=100% Hahn observed by Hazel_N on 2012-1-9 *

     On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel 
     (Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max, 
     with 2x teleconverter, at f9, 1/320 sec, ISO 400  tripod 
     mounted, mirror up), A series of images were taken. The 21:06 one 
     showed a grey column cutting across the central floor of the 
     crater from the west and then bisecting the eastern rim. All 
     detail inside is completely invisble. Some (but not all) of the 
     other images showed a more blurred view of this feature. It's 
     possible that this was a seeing ripple effect, or just the 
     natural appearance of shadings on the Moon at this time, however 
     for now this will be given an ALPO/BAA weight of 1.
