.....Tomorrow is the
Transit of Venus across the Sun! (The last one for more than a hundred
years.) In the past, transits were very important, used to measure the
size of the solar system, carefully noting how our location on Earth
changed how we saw the eclipse. In many senses, this is not going to
make a huge differences to observers of this transit. For example, the
starting times of this transit (for observers in the continental United
States) will see:
..................Venus begins to move in front of the Sun................Venus is entirely in front of Sun
Winona, MN...........5:04:31...............................................................5:22:00...(CDT)
Chattanooga, TN...6:04:27...............................................................6:21:58...(EDT)
Denver, CO............4:05:22...............................................................4:22:50...(MDT)
Seattle, WA............3:06:01...............................................................3:23:07...(PDT)
.....The
times involved were obtained from this website. The astute reader
(you) will notice that except for the time zone shifts, the times are
really not that different.
.....For
North America (barring Alaska, the Yukon, the Northwest Territories and
some of Canada's islands), the transit of Venus will be ongoing when
the Sun sets, so these times will be the beginning of the event, with
sunset as the end.
.....If
you will be in the Winona area, there will be a telescope with a solar
filter (for safe viewing of the transit) at the east end of the park
around Lake Winona. This will be set up near the John L. Schneider
Police Shelter near the parking area across from the hospital. I will
be set up from 5 PM until the Sun is no longer visible. If you are
around, I hope to see you there - if you are not, good look observing
the Transit. (After this, I will discuss my next big project.)
