I have been going out to watch the lightning bug show here in NC around 9:30 each night. Fond memories of my 10 year old daughter chasing them around the yard :) Also I check out Venus shining brightly in the NW. I see it about 10* above the horizon and see it's climbing higher each night. How far up will it go before heading back down?

 

My Sky Safari App gives me a lot of info on the planet. Right now it says it's at mag.3.9 and I can see it down as low as 4*. I see it's going to pair up with Mars next week. Have to grab one of my grab scopes to see both in the same EP view.

 

Clear skies and have a good 4th and stay safe!

I got my first view of Venus (this apparition) on 2nd June from down here on New Zealand's South Island. It was about 10 degrees altitude at sunset. Last night it was 17 degrees at sunset and made for a striking sight in the eastern sky, with Sirius further east at a similar altitude. The brightest star and the brightest planet; lovely. It's currently 90% illuminated and 11.15" apparent size, and I could make out a tiny disc in the 20x80's. The planet reaches its highest elevation on 24th October when it'll be a similar apparent size to Saturn at opposition, and 52% illuminated, and 2.5 times brighter than it currently is. Even later in the year, it will line up with Saturn and Jupiter, and becomes a thin crescent, becoming almost lost in the twilight by years end.

 

Ray.

Here's an afocal iPhone photograph of Venus that I took on June 28th using the 17" f/15 classical Cassegrain at the Naylor Observatory.

Here's the section on Venus from the July Celestial Calendar.

https://www.cloudyni.../#entry11201050

 

Venus changes very little in brightness, apparent size, and illumination during July. Venus increases in solar elongation from 25 to 33 degrees but a 12-degree decline in declination leaves it poorly placed. The brightest planet passes north of the open cluster M44 on July 3th and is at its greatest northern latitude the next day. Venus and Mars both travel southeastward through Leo this month coming within 0.5 degrees of each other on July 13th. The waxing crescent Moon passes three degrees north of the two rocky planets on July 11th and July 12th. Venus passes about four degrees south of the barred-spiral galaxy M95 on July 27th.

Thanks for the post. What does solar elongation mean?

Looked at it last night and it seems to be heading a little west now.

The elongation is the angular separation between the Sun and a planet or other Solar System body as observed from the Earth.

I was able to get an image on Friday. Nothing but clouds the last two nights but I expect to get much better images later in the year.

Last night I see it's really heading west now at a pretty good pace. Visible from where I live to 10 pm now, barely.

Ah, I see it getting close to be full now. I'll have to put my scope to it.

Venus actually decreases in illumination, from 90% to 82%, during July.

That might actually help me here in Az. I've been experimenting with Moon and LPFs to keep it from getting blown out.

It's really moving west right now! Hope the clouds move tonight for the 3 way conjunction!

After a night of clouds, last night there was some clearing for a short time to see Venus. Mars was not visible though. It appears Venus has moved about 5* west now and hope to see the conjunction tonight.

 Here's another screenshot from Stellarium showing the positions of the waxing crescent Moon, Venus, and Mars at 1:15 UT from a latitude of approximately 40 degrees north.

I managed to view Venus at 26 degrees altitude, just before sunset, last night. Currently 84% illuminated, it made for an exquisite sharply defined site using a 5.5mm wide angle eyepiece. I could make out just a hint of darker cloud near the terminator (although my brain may have made that up).

I observed Venus again last night using Canon IS 15x50s and the 5" f/5 refractor and 17" f/15 classical Cassegrain housed in the Naylor Observatory's French Dome.  I also saw Mars through the 5 and 17" telescopes, which will probably be my last observation of the Red Planet for quite some time.  

Mars was about 5 degrees above the horizon at the time and Venus about 8 degrees.  The two planets were separated by approximately 5 degrees.

I've included a screenshot (click to enlarge) from Stellarium.

I'm trying to get a decent cell phone shot of Venus, and have taken advice from a couple of CN threads, which include decreasing the brightness on the phone and using a red filter. Tonight I had a go with this new information, and the results are a bit blah, but better than I've had previously. The planet was 77% illuminated and at 29 degrees altitude.

I managed to get an image yesterday, right after sunset at 20° altitude.

0 gain, 5ms exposures, 20,000 frames. Best 10% stacked in AS3. Sharpened in RS6.

A lovely image. I don't expect to capture one that good with the smartphone.

Looked at Venus last night and it has moved about 20+ degrees from a month or two ago. From the NW to just past dead west. It's also a little lower than it was before.
