Venus and Mars are in conjunction on July 13th. Venus (magnitude -3.9) passes 0.47 degrees north-northeast of Mars (magnitude +1.8) at 14:00 UT. 

 

The waxing crescent Moon passes three degrees north of the two rocky planets on July 11th and July 12th.  The Moon, Venus, and Mars lie within a circle with a diameter of 3.6 degrees at 12:00 UT on July 12th.

I hope it's not cloudy on the 13th. I'll have to listen to Paul McCartney's "Wings Album" called "Venus and Mars" also. It has  yellow and red billiard balls on the cover to depict a conjunction of the two planets.

Thank You for posting that link! I'm not sure I ever listened to the whole album B4, - I enjoyed it! It's a good Solar system that keeps the Big Billiard Balls from banging into each other.smile.gif

This is how that part of the sky will look on the evening of July 13th.

I see Venus and Mars just broke through the 1* separation today. Hope we have clear skies for the big night in two days! Gonna get a small scope and a 1* + eyepiece to see them in the same view.

We've been very lucky with the weather here in my part of New Zealand, so I've been following Venus and Mars for the last five days. Tonight was another classic, crisp winter's evening, which was great for the conjunction. My photography abilities are very limited. One taken by holding the camera up to the telescope's eyepiece, and the other taken with an old point-and-shoot.

Thanks for the heads-up on this.  I've been watching over the last couple of days.

Moon Venus Mars 07-11-21 CN.jpg

 

Just for fun, I shot this nice alignment last night at 9pm local time (click on it), in prep for tonight's conjunction. Olympus E-M1, Oly f/2.8 40-150mm Pro at 97mm, 1/4-sec at f/2.8, ISO 1600, somewhat cropped.

 

One thing I found interesting, is that Mars is about mag 2, and Venus is about mag -4... so observing this pairing in a pair of binoculars is a nice depiction of the difference between six orders of magnitude.

 

And I never get tired of seeing how much these objects move, over the course of 24 hours. No wonder the ancients were mystified.    biggrin.png

Thanks for the "Like".

 

Be sure to look tonight, as well as tomorrow. For those of us in the US, they'll be a little closer to each other tonight.

Went out twice but clouds too dark/thick. Maybe tomorrow.

I was afraid that would happen to you.   gaah.gif

 

I looked at this:

...earlier this afternoon, and saw that there were lots of clouds forming and drifting your way. It's clear-but-hazy, here.

Got to see this conjunction yesterday evening with my C5 and 20/14 XW eyepieces which fit both planets into the same FOV.  Very nice view before clouds came in around 9:20 PM.  Will try again tonight with the Tak 76 DCU.

Smoke got me last night all the way up to 6,000 feet, but tonight I was able to catch the pair in the backyard.  Nice little pair at 49x in the AT72EDII.

I had to do some driving to get to a spot where I had a slight chance of seeing Venus and Mars due to encroaching low clouds after sunset.  The waxing crescent Moon was well above the clouds but I had almost given up hope of seeing the conjunction when I was able to sweep up Venus from darkening clouds with Canon IS 15x50s. 

 

A hole opened up and I was able to then employ my 80mm f/5 Orion ShortTube 80 achromatic refractor and an 8-24mm Tele Vue Click Stop zoom eyepiece (17 to 50x).

 

It wasn't too long before the clouds covered the two planets again.  On the way home, I was treated to a fine display of lightning in the north.

A repost from this thread; these were shot 2021/07/12 19:25-19:50 GMT+10 15.1850° N, 145.7467° E. The sky was mostly clear to the West, but a massive cloud front came in from the East at 19:50, bringing torrential rain, thus ending the session. The clouds, however, added interest to what would have otherwise been generic images. No mount was used for these (no time for set up or tear down, what with weather pending), just a camera tripod and intervalometer:

Got lucky and had clear skies tonight. Had good looks at Mars/Venus/Regulus/Moon. I used both 7x50 "Stellar" binoculars, and 15x70 "Barska" binoculars. Did not take any scopes out, - but a nice conjunction, I might have missed if not for original post.

I hadn't been following the news of this conjunction but I noticed the moon when I was out bringing in the garbage cans from the curb tonight. I keep a Meade Infinity 80mm f/5 achro with a 16mm Nagler on a video tripod near the back sliding door, mostly for birdwatching. On a lark, I decided to take it out on the back deck for a five minute view of the Moon. While I was out there I noticed Venus just about to set so I aimed the scope at it. That's when I noticed a second planet in the field of view. I thought it must be Mecury, and attributed the reddish hue to its low position in the still bright sky. After coming inside and looking up the positions of Venus and Mercury on my phone, I discovered it was indeed Mars. I stumbled on this nice conjunction by pure blind luck.

The conditions were poor.  Here's an iPhone photo of Venus that I took shortly after locating it with the 15x50s.
