Summer 2016 meteors July 26, 2016

It’s meteor shower season, and The summer meteor showers are ramping up!

The Delta Aquariids are in progress now. Although the peak is expected to fall on July 28, this is a long, slow shower, worth watching for at least a week after the peak. Don’t expect to see a lot of meteors though. Even at its peak there are only 10 – 20 meteors per hour (or about 5 minutes between meteors.) The radiant is highest at around 3 AM this time of year, so that would be the best time to observe if it weren’t for the waning Moon in the last week of July. Going out around 1:30 – 2:30 on the 28th gives a good combination of reasonably high radiant and a low Moon.

While you’re out looking for delta Aquarius, watch for Perseids too. Luckily, Perseus isn’t far from Aquarius. Check out this story from EarthSky on how to tell them apart.

While the Perseids don’t peak until August 11 or 12, you should already be able to spot a few. The real show should be the early morning of August 12, and continue through the morning of the 13th and maybe the morning of the 14th. Some experts think this could be a spectacular year, with rates of 200 per hour at the peak (that’s about 3 meteors per minute!) Better still, a waxing moon means dark skies most of the early morning hours. The best time to view will be around 3 – 5AM, when the Moon has set, Perseus is high, and twilight hasn’t really started yet. Here is a map for 4:30 AM on August 11 with both radiants marked.

Urban Observing June 2016 – Planets version June 7, 2016

I’m a little overloaded these days, but there’s so much good stuff in planets I wanted to get those out there.

Mars Opposition was on May 22, and it’s closest approach on May 30, so early June is still a great time to check out the red planet.

It’s not far from Saturn, which is at opposition on June 3. It has a nice tilt now too, so it’s a great month for cell phone pictures through a telescope.

Jupiter is still a great evening target. Look for it high in the south at sunset. It’s only 1º from a first quarter moon on the 11th.

Morning observers get some of the easiest viewing of Mercury the first 2 weeks of the month. Of course, the early sunrise means you’ll have about a 15 minute window 30 – 45 minutes before sunrise to catch it. Greatest western elongation is on the 5th, but the best angle relative to the horizon is the 13th (at least at 42º latitude.) Binoculars will help.

Venus fans are out of luck. Superior Conjunction is on the 6th, so it’s lost in the Sun’s glare most of the month. If you’re up for challenge, start watching for it in the evening at the end of the month.

The lowest full moon of the year will be on June 20. If you’re a fan of optical illusions, check it out – the low altitude enhances the Moon Illusion.

Using binoculars, and a clear ENE horizon, you can spot a very old Moon and Mercury tomorrow morning. About 45 minutes to an hour before sunrise, go out and look for the bright Star Capella in the north east. Drop your view about 5° toward the horizon, and scan to the east. With a little luck, Mercury and a very old old moon will pop into view.

June 2-3, 2016 is the night of Saturn’s opposition. This world is now opposite the sun in Earth’s sky. How to see Saturn and enjoy it as its best!
