TLP Repeat Illumination/Libration and Earthshine predictions for: USA AK Anchorage



Ill is percentage illumination of the Moon
*Indicates a repeat illumination and libration event to within +/- 1 deg for both
A non-* indicates just repeat illumination to within +/-0.5 deg

2020-Jul-13 UT 12:33-12:59 Ill=45% Aristarchus observed by Sekiyuchi on 1970-7-26 

     Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan, 
     36" reflector) "Polarimetric and photoeletric anomalies on Moon" NASA 
     catalog weight=5. NASA catalog ID #1268. ALPO/BAA weight=5.


2020-Jul-23 UT 06:52-07:21 Ill=8% Aristarchus observed by Darling_D on 1990-2-28 *

     On 1990 Feb 28 at UT 00:05-00:13 D. Darling (Sun Praire, WI, USA, 3" 
     refractor, c36) observed Aristarchus "flare up several times 2x > 
     before". Cameron suspects that this is due to cloud cover reflectivity 
     on the limb of the Earth. The Cameron 2006 catalog ID=391 and the 
     weight=0. The ALPO/BAA weight=1.


2020-Jul-23 UT 06:52-07:21 Ill=8% Lambert observed by Fryback_D on 1990-2-28 *

     On 1990 Feb 28 at UT 00:05-00:13 D. Fryback (Madison, WI, USA, 8" 
     reflector) noted that Lambert crater looked like a 9th magnitude star-
     like point of light. The Cameron 2006 catalog ID=391 and the weight=0. 
     ALPO/BAA weight=1.


2020-Jul-23 UT 07:18-07:21 Ill=8% Picard observed by Unknown_English_Observer on 1877-5-15 *

     East of Picard (56E, 15N) 1877 May 15 UT 20:30 Observed by an
     unknown observer (in England?) "Bright spot. (white patch) 
     there unlikely to be bright at sunrise normally)." NASA 
     catalog weight=3. NASA catalog ID #189. ALPO/BAA weight=2.
