The clouds moved in last evening, preventing us from seeing the first of the "supermoons". But still, after a few days of sunshine, rain was welcome. Still, it would be lovely if either the August or September nights are clear. :)

Long gone are my days of walking in the dark of the early morning hours. Looking forward to that again come autumn. And the sun sets late these days, so it's not often I am up seeing the vast vista of the night sky. How I miss it!

There's a 'double star' in the southwest at dusk (for Northern Hemisphere viewers). It's reddish Mars passing just north of bluish Spica. Mars is slightly brighter but the pair is evident even with city lights. Look for Mars to pass near Saturn next month.

A bright fireball passed over the southeast US overnight, and was viewed by many people and captured on at least one video. Nearly 100 reports on the American Meteor Society give magnitudes anywhere from -7 to -27. Impressive!

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.

Just got a Google Sky Map app, but I haven't had a chance yet to try it out at night. So far it looks interesting, albeit a tad jerky. It seemed to have the sun out of place: everything else looked fine :) Maybe it'll help me do better with constellations and stars--I can only consistently identify Orion and the Dippers

Now my days are swifter than a post: they flee away ... my days are swifter than a weaver's shuttle

Out camping this weekend, ( more on that on the right thread ), and I had the sudden urge to check if the outhouse door was working. ;)
As I was on my homeward journey to the tent I glanced upwards to see a beautiful view of the stars, with only the nearby trees blocking it. The Milky Way was almost pefectly aligned with the treeline made by the path I was on.
I was then treated to one of the brightest fireballs I have ever gazed upon. It was followed not five seconds later by the familiar streak of a meteor.
There was also a quick bright glow in the sky, though I do not know if this was at all related to a meteor shower.
Definetly one of the highlights of the trip.

Ahh, fireballs are awesome! Very cool link, stargazer. Puddleglum, I read this article on SpaceWeather, so possibly you saw some early Perseids. But, from that link, even more likely are the Southern Delta Aquariids, which are at hand, and are apparently "rich enough in fireballs to merit attention". :) We have thick cloud cover here for a few days now, I'm outa 'luck' until that clears.

All the best with the Google Sky Map app, aileth!

Ah, Puddleglum, your comments here and in the Camping thread make me eager for those crisp autumn days and nights that are on the way, with stars shining over the campfire and the Milky Way lighting up the sky.

Very cool about your fireball sighting too!

Jo mentioned the Southern Delta Aquariids, which are a small but bright shower (and have even gotten some attention on the Weather Channel, with a video report from Sky and Telescope's J. Kelly Beatty. The Moon phase for that shower was more favorable than it will be for the Perseids in a couple weeks (when a near-full moon will light things up for most of the night).

I also went out this weekend to stargaze, though my view was hampered by city lights. Saturday evening I noticed Mars, now between Spica and Saturn, in the southwest. I walked a few blocks to the south, where I have a limited view of downtown Minneapolis, to watch the finale fireworks for a local summer festival, the Aquatennial. Just to the upper left of the man-made show was nature's show - lightning illuminating clouds in the distance. It was quite pretty.

About half an hour later I returned outside to see a magnitude -7.5 Iridium flare and was surprised to see the sky was now rapidly clouding over. The flare was visible through a small gap in the clouds.

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.

Mid-August is the time to watch for the Perseid meteors, one of the year's most reliable showers, producing up to 100 meteors per hour under excellent conditions.

This year, however, will not be ideal. The moon is just past full for the shower's peak at around 0 hours UTC August 13 (early evening August 12 in North America). It will wash out a lot of the meteors, but the bright ones may still shine through. Read more here.

Early-morning risers may want to keep a close eye on bright Venus, low in the sky in twilight. Jupiter will rise up to meet it, passing closest on August 18, but the pair is worth watching before and after that date.

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.

I stumbled out of bed this morning around 0530 to catch the solar system's 2 brightest planets rather close together. Venus and Jupiter are about 2 degrees apart now but will be very close Monday morning. But from my northern latitude they are quite low in the morning twilight and don't get very high before the sun blots them out. And this morning the clouds were rapidly moving in, so I caught them only briefly before the overcast came.

Read more about this close conjunction here.

In the evening sky, Mars and Saturn will be close together next week.

Very cool! It's fun in a different way when that happens—seeing a flare through a gap.

We have had so much cloud cover that there was no chance of seeing the Perseids in our area. I think this is the first summer in quite awhile I have not been out watching. But, yes, that just-past full moon would have whited out the sky even if it was clear.

As our weather is clearing later tomorrow, I hope to arise early Monday morning to see the Venus/Jupiter conjunction. Thanks for the link, 'gazer. :) And good to hear you managed to see them, albeit briefly.

/edit near 7 a.m. EDT Monday: Success for viewing Jupiter and Venus—beautiful! I will post more details later. :)

I walked out of the house at 5:45 yesterday morning, when the first hint of dawn was in the lower sky. Only a couple of short blocks away I rounded the corner and looked up in awe. There they were in all their glory—Venus and Jupiter! Higher than I thought. Clouds were supposed to have dominated the early morning sky, but those obstructions were nowhere to be seen. What a treat! I wish I had brought my binoculars, but I dashed out of the house too quickly and forgot 'em. :P

Then I went on a long walk in the very fresh air, so periodically I'd catch a glimpse of them again between the trees. Pretty, pretty.

I'm glad you saw them on Saturday morning, 'gazer. :)

Sounds like a very pleasant morning, jo! Glad you got to see them at their closest.

It was overcast here yesterday. There is good news though, Venus and Jupiter will meet again in less than a year, this time conveniently placed for those of us who aren't morning people. ;))

On June 30, 2015, they will be separated by only 20", about the same as this time, and even in almost the same constellation (eastern Cancer/western Leo), but in the evening instead.

The ISS has been passing overhead during recent evenings as well, and I've been dodging clouds and haze to see it the past week or so. Last night I was fortunate enough to see 2 consecutive passes, one during strong twilight and the next about 90 minutes later.

But all night, Aslan and the Moon gazed upon each other with joyful and unblinking eyes.

You may have heard about yesterday's big solar flare which may have been pointed directly at the earth. Now keep an eye to the sky for possible auroras (northern or southern lights), especially if you live above latitude 45 degrees or so.

It is expected to arrive at 1200 GMT Friday (0700 US CDT), so check it out if your skies are clear the next couple nights. Read more here, and spaceweather.com will likely have updates.

Meanwhile, we've just passed this year's Harvest Moon, and October's Hunter's Moon will feature the year's second total lunar eclipse. More details to come...

The year's second total lunar eclipse is coming this week! It's centered on the Pacific side of the earth, so western North America will see parts of it early on the morning of Wednesday, October 8, while the very eastern parts of Australia and Russia will see parts of it early on the evening of the 8th. Places like New Zealand, Alaska, and Hawaii will see all of it.

A visibility map, along with contact times and what to expect, is shown here. (Here in central North America, the moon will set while still partially eclipsed).

Just as Mars was near the moon during last April's event, this eclipse also has a nearby planet - but unless you have a dark sky with minimal light pollution, you'll probably need binoculars. Uranus will be about 1 degree from the moon. A finder chart and more details are in that same article.

At the moment, clear skies are forecast here for Wednesday night.

I'm trying to stock up on as much sleep as I can before Monday (baby coming then, if not sooner ;)) ). Still... it WOULD be cool to see another blood moon. I'll have to think about whether I want to get up at 5am to see it or not. ;)

I just took a photo of the moon at 9.30 local time (GMT+13 hrs).
Still looks nice and normal. I really need to get to bed, been up too late in last two nights. If the cat wakes me in the night I will try to go out for a new photo and look.

There, shining in the sunrise, larger than they had seen him before, shaking his mane (for it had apparently grown again) stood Aslan himself.
