Stargazing What's Happening in the Night Sky? Upcoming Astronomy Events to Look Out For!

[Sorry!]

Sounds like Antares (red toward the south) and Arcturus (orange, overhead in the evening).

After looking at pictures of Antares it does look like it could be what I'm seeing. Although the object I see looks relatively smaller than most of the other stars around it.

And yes I am looking to the south when I see the other object. Pictures of Jupiter do look pretty similar. I'll try to get pictures tonight guys. thanks :D

 

[hypatia]

November is perhaps my favorite month to watch the sky. It of course, is the hunters moon, but Saturn hangs out just to the left of it for the next few days.
Keep a eye out 17th, The Leonid meteor showers peek performance!

Earth v. Moon

Sorry, I'm a newbie here and didn't know how to start a new thread, so I figured I'd post a question in this one since it has a lot of subscribers.

I'm arguing with a friend about how a half-Earth would appear from the Moon. Since we see the Moon in phases, it makes sense that watching the Earth from the Moon would also offer the same phenomenon, Full Earth, Half Earth, New Earth. My question is if one is looking at a Half Earth from the Moon, would the shadow line appear horizontal or vertical.

My belief is that since the Moon is in a roughly equatorial orbit around the Earth, then the equators of the two objects are facing each other, with their axes within a few degrees of being parallel. Since we see the Half Moon as vertical from here, I conclude since there is no mechanism I can envision which would alter the perception, it should appear as a vertical line on the Earth as well.

My friend believes the shadow line should appear horizontally across the Earth.

I'd welcome any comments or explanations.

My apologies. I figured out too late how to start a new thread and did so. Please post any responses at the other link, https://www.physicsforums.com/showthread.php?p=2452328#post2452328"

Thanks.

Thats simple really look at the google results from "earth images from the moon"

hope that helps, a picture is worth a thousand words they say

Have you heard about that? A huge meteor (bolida) hit the atmosphere in 28th February somewhere in Hungary or Slovakia, at the border. It is possible that some remnants hit the ground as well. A lot of people heard ans saw the blast, there are seismology data as well. These are now under evaluation.

[bcmarshall]

Thanks. No, I hadn't heard about it. I'm having my Hungarian native uncle translate it for me tomorrow.

 

[Telmerk]

Hi,

I recommend the hirek.csillagaszat.hu website, as a trustworthy source of astronomy news in Hungarian. (non-profit, and the news are edited and reviewed by professional and amateur astronomers together.)

http://hirek.csillagaszat.hu/meteoroidok,_meteorok/20100301-tuzgomb-magyarorszag-felett.html
Title is: "Now it is clear: a bolid has exploded over Hungary"

Kind regards,
TtM

 

[Mu naught]

The moon is in conjunction with Antares right now. Go take a look!

Two Asteroids to Pass by Earth Wednesday
http://www.jpl.nasa.gov/asteroidwatch/newsfeatures.cfm?release=2725

Asteroids 2010 RX 30 and 2010 RF12 will make their closest approach to Earth this Wed. At time of closest approach for 2010 RX 30 (2:51 a.m. PDT), it will be approximately 154,000 miles (about 248,000 kilometers) above the North Pacific, south of Japan. At time of closest approach for 2010 RF12 30 (2:12 p.m. PDT ), the asteroid will be approximately 49,088 miles (about 79,000 kilometers) above Antarctica.

 

[gau_physics]

why auroras exist near alaska ??

Its bcoz of something called "Magnetc bottle" phenomenon. Near poles Earth's magnetic field lines converge.

 

[AlphaOmega3fa]

Anyone checking out the Geminid shower?
I believe it starts tonight through 12/15

 

[hypatia]

I was out this morning around 2AM, and lost count after seeing about 30. I believe it was at its peek last night. It was beautiful.

 

[Jonathan Scott]

I was out this morning around 2AM, and lost count after seeing about 30. I believe it was at its peek last night. It was beautiful.

I had a brief look for 5 minutes last night, through thin patchy cloud, and saw one small flash and one surprisingly bright reddish-orange glowing ball which seemed to move relatively slowly, leaving a bright trail, visible for a few seconds.

 

[russ_watters]

How long were you out?

 

[hypatia]

I was frozen stiff under perfectly clear skies, by 4AM.

 

[vijay.wps]

The darkest I have ever seen was one night when a magnitude 6.9 star could be seen, but this is very rare. Magnitude 11 is usually considered near the limit for a good 8 inch telescope. I heard from a math major who's taking the astronomy class at my school that there is a nebula or a new star forming in Orion's belt.

Lunar eclipse and winter solstice to coincide, first time since the year 1378

Coincidences: This lunar eclipse falls on the date of the northern winter solstice. How rare is that? Total lunar eclipses in northern winter are fairly common. There have been three of them in the past ten years alone. A lunar eclipse smack-dab on the date of the solstice, however, is unusual. Using NASA's 5000 year catalog of lunar eclipses and JPL's HORIZONS ephemeris to match eclipses and solstices, author Dr. Tony Phillips had to go back to the year 1378 to find a similar "winter solstice lunar eclipse."

[Redbelly98]

Here are the times at which the upcoming lunar eclipse will occur.

Night of Dec. 20 / morning of Dec. 21
The three times listed are Pacific (USA) and Eastern (USA)

Partial phase begins: 10:33 PM / 1:33 AM
Total phase begins: 11:41 PM / 2:41 AM
Total phase ends: 12:53 AM / 3:53
Partial phase ends: 2:01 AM / 5:01

 

[mugaliens]

Well, I got a crappy hand-held pic...

Sorry, it's the best I could do.

I did see the ruddy red after midnight, though... Wonderful!

Greetings:

I am looking for a formula to find the duration of sun's meridian transit for a given location and date.

Can anyone help out?

 

[hypatia]

Saturn has been a joy to view this month. Even with a very small scope, you can clearly see the rings. If you look to the east, you will see 2 bright objects. One is the star Spica in the constellation Virgo, the slightly brighter one above it, is Saturn.

 

[toxicity_27]

Saturn is still out. Second time I've seen it in 5 years. Very bright, and it seemed as though I could see between the planet at the rings. I may be crazy though.

 

[Gliese123]

Someone who knows if anything astronomical is happening in the northern hemisphere (Northern Europe) this July? :)

The sunspot behemoth isn't yet facing our planet, but was spotted today (Nov. 3) by NASA's Solar Dynamics Observatory (SDO) satellite. The spacecraft 's photos of the giant sunspot show the solar region as it comes into view on the northeastern edge, or limb, of the sun.

When it does turn our way in the days ahead, it should be an "easy target for backyard solar telescopes," according to SpaceWeather.com.

 

[Drakkith]

It's November now ricci!

 

[Telmerk]

"When it does turn our way in the days ahead, it should be an "easy target for backyard solar telescopes," according to SpaceWeather.com."

Some of my friends told me it is also visible with the naked eye (using protection of course).

 

[davenn]

good view of totality after the clouds cleared minutes before totality started :)

looking forward to the Venus transit next year, last one of the pair and a long time before the next set. no one alive today will see it.

cheers

[toxicity_27]

Quadrantids Meteor Shower tonight. Starting at about 3AM when the moon sets to dawn will be the best viewing time. Only happens today.

Thanks for the heads up :)

Have only arrived back in the country after xmas and NY overseas and haven't had a chance to catch up on up coming events

[Drakkith]

Start planning your trips now. On June 5-6 the last transit of Venus across the Sun for the next 105 years will occur. Observers in the US can only see part of the transit, as it starts to occur at sunset.

On June 5-6 the last transit of Venus across the Sun for the next 105 years will occur.

In which all countries is it view-able? Please let me know.

 

[Borek]

Follow links from the wikipedia article to find out details, it is all there.

Yup, the map with the caption "Where the 2012 transit will be visible" is pretty informative.

Annular Solar Eclipse

May 20 - Annular Solar Eclipse. The path of annularity will begin in southern China and move east through Japan, the northern Pacific Ocean, and into the western United States. A partial eclipse will be visible throughout parts of eastern Asia and most of North America.

 

[Borek]

Bump: Venus transit is on Wednesday.

 

[Drakkith]

Bump: Venus transit is on Wednesday.

Woohoo!

 

[dipole]

Tuesday for the United States.

 

[chemisttree]

Tuesday around 5:00 pm Central is first contact and it lasts just over 6 hours... well past sunset. That's Wednesday about midnight Central European Time. Sorry Borek. You should be able to follow it via GLORIA though.

 

[Borek]

If not for the weather it should be visible here around sunrise.

 

[turbo]

I just checked and I seem to have misplaced my welders' glass. May have to go buy another...

 

[davenn]

finally got my camera and solar filter mated to the scope, now all I need is for this contineous rain to disappear.

Transit starts, here in Sydney, at 08:09 eastern Australia time (local time) ~ 1 hour after sunrise and goes through to ~ 14:44 hrs local time


cheers
Dave

 

[chemisttree]

It's here! Just snapped a photo of it through my homemade Carton 60mm f16.7. I used a Scopetronix Maxview 40mm eyepiece equipped with a Baader Contrast Booster filter attached to my Sony F717. 1/1000 sec a f8 afocally with Baader Solar Film. Levels, resizing, unsharp mask using Photoshop 7.

Great. I've been looking forward to seeing this for the past week, but it began to rain before it got here, so I can't see it. Good thing I've got this.

 

[davenn]

nice pic chemistree

well done, its just coming to an end here in eastern Australia and I missed 3rd and 4th contacts the weather finally totally crapped out
