Hi

I'm working on that. I'm going to look for a nice camera for my telescope. I'll post them on the meetup page when I do.

Hi all,

Thanks for that post. That hoax is silly.

I saw Mars last night with my scope. It rises in the northeastern sky. You
won't see it til 2 or 230am right now (cause of the NY haze). I Could easily
see the ice cap through my scope.  It's dim til it rises above the haze.

Was looking at Jupiter, Neptune and Uranus too. Great red spot was visible
and was watching 1 of the moons pass in front of the planet (Jupiter).  Real
nice.

If it's clear this weekend I'll be out there. If anyone wants to join me
just let me know.

Hi:

I am not sure when this meetup actually meets up, but here is some
information about a hoax email that is circulating regarding Mars appearing
as big as the moon August 27, 2009.  This is from earthsky.org.

Fwd: SEE TWO MOONS ON 27TH AUGUST. 2009 Should be spectacular! Truly a once
in a lifetime experience!

It?s happening again. People are clamoring for information about an amazing
spectacle involving the red planet Mars. An email is circulating suggesting
that ? on August 27, 2009 ? Mars will appear as large as a full moon in
Earth?s sky. The version I saw actually included a powerpoint presentation,
suggesting that Mars and Earth?s moon will appear as a ?double moon? in late
August 2009.

It sounds amazing! Can it possibly be true?

No. It can?t. The email is a hoax. It has circulated every summer since
2003. Mars can never appear as large as a full moon as seen from Earth, and
Mars will not even be at its brightest in August of 2009.

In fact, in August of 2009 Mars is a relatively inconspicuous dot of reddish
light in our eastern predawn sky. It did appear near the moon this month ? a
waning crescent moon visible before dawn ? on the morning of August 16. That
waning moon might have made Mars slightly more conspicuous than it would
have otherwise been. Now the moon has moved on in its orbit around Earth,
leaving Mars behind, and unless you know exactly what you are looking for,
you probably will have trouble finding Mars for the rest of this month.

Ah, Mars. World of dreams and visions. Mars is the world orbiting one step
outward from Earth?s orbit. This world is slightly smaller than Earth ? but
slightly larger than Earth?s moon. Mars is also much much farther away than
Earth?s moon. It?s hard to comprehend what little specks the planets and
moons are in contrast to the vastness of space, but let me put it this way.
Earth?s moon is about a light-second away. Traveling at 186,000 miles per
second, light bouncing from the moon?s surface takes about a second to reach
us here on Earth. Meanwhile, light from Mars takes much much longer to reach
Earth ? from several minutes to about 20 minutes ? with the difference being
the result of Earth?s and Mars? motions around the sun. In other words, when
Mars is on the same side of the sun as Earth, its distance from us is less
than when it?s on the far side of the sun from us.

The moon is much closer than Mars, and that?s why we see the moon as a
bright disk in our sky. Meanwhile ? to the eye ? Mars never appears as
anything but a ?star.?

So how did this rumor of Mars-as-big-and-brig­ht-as-the-moon get started? It
started with an actual event, in 2003. On August 27 of that year, Earth and
Mars came very slightly closer than they?d been in nearly 60,000 years. Our
two worlds, center-to-center, were about 35 million miles apart ? just over
three light-minutes apart. The last people to come so close to Mars were
Neanderthals. Astronomy writers like me had a field day that year, talking
about Mars at its closest. Was it a spectacular sight? Yes! It looked like a
dot of flame in the night sky. But was Mars as big and bright as the moon,
even at its closest in 2003? Never.

What is happening on August 27 of 2009? Nothing, really. By coincidence,
there will be a reddish star near the moon on August 27, the star Antares in
the constellation Scorpius. The name Antares or Ant-ares means ?rival of
Mars.? Antares is sometimes called Mars? rival because both Antares and Mars
appear reddish, and because the planet Mars sometimes appears brighter than
this star.

This August, though, Antares appears brighter than Mars does in Earth?s sky.
Will some people look outside on August 27 ? see Antares near the moon ? and
think this reddish star is Mars?

Probably.

And so the legend continues

thank you for the info; I kind of thought it was Venus; can't wait to have a
telescope meeting somewhere; can't get on my roof anymore and really, really
miss looking at the sky.

Hi

It's probably Venus. Mars rises like 130
Am or so. Visible after 2 or so. Venus rises later on. It's really bright ad
you describe.

That was when everyone said that Mars would be the size of the moon in the
earth's sky. Thank God we have science to counter these urban legends!
Tonight, Mars should be near the moon still, even in Asia!  May have changed
a bit in the past 4 days but not by too much!

If you?re up before dawn on Sunday morning ? the morning of August 16 ? you
can use the waning crescent moon to locate the planet Mars. Look for Mars
about two finger-widths to the moon?s right or upper right. (Hold your two
fingers an arm length away.)

Jawad,

You are probably reading a very exaggerated description of the opposition
from Aug. 2003.

Right now the best planet to see is probably Jupiter, which should be easy
to pick out if you look towards the south at night time.

I am currently vacationing in Asia and I dont see mars at all. From what I
read, mars was supposed to be the brightest object in the night sky and even
visible at daytime all over the world. Does anyone know what happened? Is it
visible in NYC?
