TLP Repeat Illumination/Libration and Earthshine predictions for: Greenland - Nuuk



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


2018-Jun-19 UT 01:43-03:01 Ill=35% Aristarchus observed by Hobdell on 1981-6-8 *

     On 1981 Jun 08 at UT01:48-02:45 B. Hobdell (St Petersberg, FL, USA, 10 
     and 4" reflectors) could hardly see Aristarchus crater, however at 
     01:48UT it brightened in blue for about 3 minutes. Then at 02:20UT 
     there was a bright flash, and by 02:25UT the crater was very bright, 
     but by 02:45UT it was no longer visible. Cameron 2006 catalog ID=144 
     and weight=0. The ALPO/BAA weight=1.


2018-Jun-20 UT 01:43-03:12 Ill=46% Linne observed by Buckingham on 1867-8-6 *

     Linne 1867 Aug 06 UT 21:00? Observed by Buckingham (England?) 
     "Crater in darkness, he saw a "rising oval spot". Other obs. 
     saw it as a triang. Bold black spot pointing to earth, slowly 
     diffused white & drift of white on slope of pyramid. (indep. 
     confirmation?)" NASA catalog weight=5 and catalog ID #155. 
     ALPO/BAA weight=2.


2018-Jun-20 UT 01:43-03:12 Ill=46% Ross_D observed by Harris on 1964-5-18 *

     Near Ross D (23E, 12N) 1964 May 18 UT 03:54-04:53 Observed by Harris, 
     Cross et al. (Whittler, CA, USA, 19" relector x720, 8" reflector x322, 
     S=G) "White gas obscuration. Moved 20mph, decreased in extent. Phenom. 
     repeated. Drawing." NASA catalog weight=5 (very high). NASA catalog ID 
     811.


2018-Jun-24 UT 01:44-03:29 Ill=85% Gassendi observed by Grego_P on 2011-10-7 *

     On 2011 Oct 07 UT 21:45 Gassendi observed by P. Grego (St 
     Dennis, UK,300m Newtonian, x150, seeing III, intermittent cloud) 
     - whilst producing some sketches of the crater - observer 
     noticed a faint point of light inside the shadow filled 
     interior, two thirds of the way out from where the central 
     peaks should have been, towards the SE rim. Some uncertainty in 
     being sure about this spot and after interuption by cloud it was 
     not seen later that evening. ALPO/BAA weight=1 to refelct 
     uncertainty of observer.


2018-Jun-25 UT 01:44-02:47 Ill=91% Torricelli_B observed by Cook_MC on 1989-1-18 *

     M. Cook of Frimley, UK observed a brightening of the crater during
     this observing session. The cameron 2006 extended catalog ID=346 and 
     weight=3. ALPO/BAA weight=2.
