Today April 29, 1921 Birth of Cornelis de Jager, Dutch astronomer. Studied the Sun and solar eclipses. and in 1976 Partial Solar Eclipse which I observed on 29 April 1976 in Hasselt, Belgium. My first solar eclipse. any many to follow ... and in 1995 During the 20th Century there were 11 solar eclipses with a Greatest Complete Duration (GCD) larger then 4 hours, and during the 21st century there will be 7. The greatest GCD of the period 1900-2100 is that of the eclipse of 1955 December 14, namely 4 hours 26 minutes 30 seconds. The last eclipse with GCD exceeding 4 hours was that of 1995 April 29, with GCD = 4 hours 05 minutes 48 seconds, at longitude 78°W, latitude 5°S. The next eclipse with GCD larger then 4 hours will be that of 2010 January 15 (3 Saros periods after the record one of 1955 December 14), with a GCD of 4 hours 13 minutes 06 sec. and as well in 1995 I observed the Annular Solar Eclipse of 29 April 1995 in San Pedro de la Bendita, Ecuador from the northern edge. My first edge solar eclipse. and today in 2014 Next annular solar eclipse which will not be a central solar eclipse on earth. This limit solar eclipse is like the one of 03 October 2043 a miss, the two only exceptions next century. The central line of the solar eclipse will not be visible on earth. Both central lines are near the South Pole. This century there where as well two misses, 18 March 1950 near the North Pole and 30 April 1957 near the South Pole. The value of Gamma for the April 29, 2014 eclipse will be (to 3 significant figures) exactly equal to minus 1.000 (-1.000). This is fairly rare. Following solar eclipses that have a value of Gamma equal to 1.000 (both positive and negative) at maximum eclipse are –1339 Jul 03 (A-), -1320 Jun 04 (T+), -0869 Sep 25 (A+), -0196 Feb 01 (P), 2014 Apr 29 (A-), 2507 Apr 13 (A-) and 2662 Jan 12 (A+). Ref. SLK 6/99 and Michael Gill 4/01. Meeus calculated all non-central total or annular solar eclipses during the period 1950-2050: 1950 Mar 18 -0.9990 non-central annular; 1957 Apr 30 +0.9990 non-central annular; 1957 Oct 23 -1.0024 non-central total; 1967 Nov 02 -1.0008 non-central total; 2014 Apr 29 -1.0001 non-central annular; 2043 Apr 09 +1.0030 non-central total; 2043 Oct 03 -1.0104 non-central annular.
