00:00:03,833 --> 00:00:07,200
ELLO THERE ECLIPSE 
ENTHUSIASTS   TRACE HERE~

2
00:00:07,200 --> 00:00:11,666
THIS WEEK IS AN ANNULAR SOLAR 
ECLIPSE     OVER THE PACIFIC 
OCEAN AND THE TIP

3
00:00:11,666 --> 00:00:15,533
OF SOUTH AMERICA. SORRY. BUT, 
THIS IS AN OPPORTUNITY TO 
EXPLAIN WHY ECLIPSES COME

4
00:00:15,533 --> 00:00:19,700
WITH FRIENDS! FIRST WE 
NEED TO FIND THE ECLIPTIC.

5
00:00:19,700 --> 00:00:22,633
HERE’S THE SKY AT SUNSET ON 
OCTOBER 5. THE BRIGHT DOT THERE 
IS THE PLANET VENUS    HEY 
GIRL!  NOW,

6
00:00:25,266 --> 00:00:29,566
TRACE A LINE ACROSS THE SKY TO 
SATURN IN THE SOUTHEAST   THAT 
IMAGINARY LINE IS THE ECLIPTIC!

7
00:00:29,566 --> 00:00:32,466
IF YOU TRACK THE MOON YOU’D NOTE 
IT RUNS ALMOST PARALLEL TO THE 
ECLIPTIC, BUT NOT

8
00:00:32,466 --> 00:00:36,033
QUITE   THEY ACTUALLY CROSS. 
THAT POINT IS CALLED A NODE!

9
00:00:36,033 --> 00:00:39,366
WHEN THE MOON CROSSES A NODE WE 
SEE AN ECLIPSE   EITHER LUNAR 
ECLIPSE OR

10
00:00:39,366 --> 00:00:42,766
SOLAR ECLIPSE   DEPENDING. IT 
TAKES TWO WEEKS TO MOVE FROM 
NODE TO NODE. SO,

11
00:00:42,766 --> 00:00:46,066
IF WE SEE AN ECLIPSE ON ONE, 
WE’LL LIKELY SEE ANOTHER IN TWO 
WEEKS!

12
00:00:46,066 --> 00:00:48,933
THE NODES WOBBLE ALONG 
WITH THE EARTH’S ROTATION,

13
00:00:48,933 --> 00:00:59,733
WHICH IS WHY SOMETIMES ECLIPSES 
ARE TOTAL, AND SOMETIMES NOT. 
KEEP LOOKIN’ UP!
