"The Closest and Biggest Full Moon of 2001!  and; How to Find the Valentine's Day Star"

Scheduled air date: 2001 Feb 05-11


This week's Full Moon—the closest to Earth of the year—will be nearly 31000 miles/49000km closer than the Full Moon of September—the farthest of the year.  Because it is closer, this Full Moon will appear both larger...


...and about 30% brighter than the Full Moon of September!
(Shown for mid-Northern latitudes around local midnight on the night of February 7th-8th.)



Betelgeuse, the brightest red star as seen from Earth, reaches its highest point in the nighttime sky at about 8:15pm on Valentine's Day (February 14).


Betelgeuse is an extremely large star, pulsating in size between about the equivalent of Mars' orbit, to that of Jupiter's!
