The Solar System in NOVEMBER 2015 :
Telescopically, a rather poor month for planetary
viewing, with the exception of perhaps the morning views of JUPITER, MARS and
VENUS as they tightly group in pre-dawn skies
.
Mercury - Not a good month for tiny Mercury, but it will
rise ahead of the sun in eastern skies in early November, not visible because
of the glare of the sun. - In VIRGO
.
Venus - A
spectacular grouping in the morning sky of MARS, VENUS and Jupiter - as well as
a waning crescent moon - on November 3, with Mars and Venus very, very close to
one-another and mighty yellow Jupiter slightly to the west of that pair. In reality, try to visualize that VENUS is
the closest of the three, with Mars not even halfway to distant Jupiter. Watch throughout the following mornings as
Mars moves westward, rising higher in the sky each morning at the same time,
while Venus slowly sinks closer to the western horizon. The grouping can be seen nearly all month in
dark skies, about 4:30 a.m. local time.
- In VIRGO
.
Mars - The red planet is now a tiny dot telescopically (4
arc seconds diameter) and slowly approaching for a favorable apparition in
2016. NOTE the grouping this month with
VENUS and JUPITER (above) - In VIRGO
.
Jupiter - Still small by comparison to it opposition in
late 2016, the brilliant yellow planet rises in dark pre-dawn skies nearly due
east; note the spectacular grouping of this planet with VENUS and MARS on
November 3 and throughout the month- in LEO
.
Saturn - The ringed planet is now in conjunction with the
sun and cannot be viewed through November.
- in SCORPIUS
METEOR SHOWERS FOR NOVEMBER
.
The crisp and cool (sometimes COLD!) night skies of
November give way to some of the deepest penetration of earth-based eyes into
space, affording thousands of normally not seen stars to glimmer into view;
along with this comes a dramatic increase in the visibility of swift and faint
meteors that will grace deep Autumn skies; the nights can cool remarkably
clear, resulting in some long glances and time spent among the cosmos. Most of the meteor showers for November are
modest, minor streams with few meteors but there are a few great showers each
year that peak in November, among them the famous LEONID meteors which may put
on a moderately good show on the evening of November 18 and into the morning
hours of Nov. 19.
.
In addition, there
are MANY other meteor showers which grace our crisp fall nights, some of which
are mysterious, some which seem to be vanished from space and others that need
observations at every opportunity!
.
November 5 -
TAURID meteors - A fair year for this normally exciting meteor shower, since
the nearly quarter moon will not set until about 2 a.m. local time. A very long duration (November 5 -12) meteor
shower, that now is defined as having TWO peaks, both seemingly coming from the
same radiant at about RA 03h 32m / DEC +22 degrees very close to the Pleiades
star cluster; this double clumping is perhaps due to two distinct breakups of
the famous Comet Encke at two different times and thus one cloud of debris
trails the other by a week. Look for the
"southern Taurid" meteors to be coming from a point somewhat south
and earlier (Nov. 5) than the "northern" Taurids which will peak
about one week later, at about Nov. 12.
For the peak on Nov. 5, the nearly new moon will not interfere with
sighting of the faintest of these
meteors until setting very late in the evening (about 10 per hour and
increasingly slightly after midnight); however, the later dates for this meteor
shower will see slightly more moonlight and thus fewer fainter meteors during
its Nov. 5-12th span. Note that this
shower is well known for producing spectacular fireballs throughout the night
and the display can last for many weeks on either side of Nov. 5.
.
November 9 -
CEPHEID meteors - Coming from the constellation of Cepheus, high in northern
skies and nearly circumpolar (neither rising nor setting but describing a tight
circle around the north celestial pole throughout the night), the Cepheids will
peak at a favorable time this year, with the nearly new moon will be absent
from the sky all night when the radiant of the Cepheids will be northwest of
overhead. This is a new meteor shower,
discovered only in 1969 and needing observations badly. The year of its discovery over 50 meteors in
a 15-minute period were recorded! So
expect to see at least 18 per hour, but only under darkest sky conditions.
.
November 12 - PEGASID meteors - Like the Cepheids, this
radiant is nearly overhead in very early evening for Northern observers in the
Americas. A remnant of an otherwise
nearly-forgotten Comet Banplain of 1819, this shower still produces perhaps a
dozen or so meteors on a good year....the meteors can be seen as early as late
October and continuing until early December.
Look for the radiant at about RA 22h 54m / DEC +10 in the winged horse
Pegasus. This year the moon is almost
new and thus not interfere with sightings of most meteors; normally it is best
to observe this meteor shower after about 10 p.m. when the radiant will have
moved into western skies.
.
November 14 - ANDROMEDID meteors - Like the Pegasid
meteors, the light from a very thin waxing crescent moon will NOT hamper
observations of this shower this year;
these meteors can be spectacular fireball meteors, leaving very glowing
and distinctly reddish trains in their wakes.
They are debris left from another famous comet, Comet Biela which split
into two separate objects in 1845; shortly later, in 1885 the Andromedids put
on a fireworks show with over 13,000 per hour seen, most spectacular
fireballs. However shortly after the
cloud passed uncomfortably close to mighty Jupiter and since only a very sparse
number per hour have been seen.
Nonetheless, like most meteor showers, any year can bring a totally
different view of the remnant cloud.
Many of these meteor are so large that they have reached the ground as
meteorites. Shower begins as early as
August 31 and lasts until December.
Radiant center is at RA 01h 40m / DEC +44 degrees, not too far from the
famous Andromeda galaxy. Try to observe
this shower throughout the evening from perhaps 10 p.m. until about 1-2 a.m.
local time and concentrate on the very beautiful fireballs that this shower is
famous for.
.
November 17-18 - LEONID meteors - An excellent year for the normally dependable
Leonids: the moon will be a western sky
crescent, setting a few hours after sunset and out of the sky pretty much all
night long, and for days before and after the peak of this year's Leonid
shower. Although the Earth is somewhat
posed out of the main clumps of cometary material from Comet 55P/Tuttle, the
parent object of this debris, there is always a chance of an encounter with a
secondary pocket of debris during any year. Most meteor scientists are expecting the peak
for this year to be slightly before MIDNIGHT on November 17 and perhaps
extending into the early morning hours when the radiant will be high in the
eastern sky. In many years hundreds or
even thousands of meteors might be seen. This year is predicted to be perhaps
an excellent showing in terms of recent years as the Earth passes near the
thick debris cloud that produced the famous 1466 meteor "rainstorm"
that was recorded over all of Europe.
Meteor forecasters are calling for somewhat of a "strong year"
in 2015 with many of the brighter members being seen as well as the many faint
meteors on a clear, dark autumn night.
Be sure to let us know what YOU observe on this famous meteor shower
during 2015... DO NOT MISS this year's
Leonid Meteors!!
