One of the most fascinating things about this one were the reports of the sonic boom — a house-shaking boom that some are saying didn’t arrive for 15 minutes after the fireball was visible. Now, by our calculations that’s a bit strange — 15 seconds would be a more likely arrival time, based on the height of our atmosphere and the speed of sound — but even a 15 second delay would be a remarkable experience.

Speaking of meteors and such, the Lyrids are here, and though they’re not the most active of showers, they can sometimes deliver bursts of 100 or more meteors per hour, so it’s worth taking a peek outside if you have clear night skies. Who knows? Maybe you’ll see a whopper like this one we saw last year!

Yesterday, we did just that with some of the icicles that were hanging from our roof. We’ve seen icicles all our lives, and were used to seeing them from a single perspective — from a few feet away as we stood and observed. This time we got up close — really close — and looked at the end of an icicle as it dripped from the sun’s warmth. We had expected to find a sort of rounded tip of ice from which the water was dropping, but it wasn’t so. What we saw was a complex crystalline structure, grooved and angular and seemingly hollow-tipped. Its delicate beauty was nothing less than breathtaking.

This has us wondering — what other ‘everyday’ things around us would reveal amazing surprises if we took the time to look up close? Sounds like the beginning of a new quest . . .

The Leonids are coming, and it sounds like it’s going to be a big one this year!  With the new moon keeping the skies dark, all we have to hope for is a cloudless sky. Asia will get a much more impressive display — estimates range as high as 300 per hour — but we can hope for 30 or so, with the possibility of some wild fireballs thrown in to the display. Get up in the wee hours of the morning, bundle up, and head outside. It might just be a night to remember =)

Hopefully you’re not covered in clouds like we are, because if our experience of a couple days past is any indication, the Orionids could give us quite a  display this year. While coming home very late (after midnight) a few nights ago, the sky was suddenly illuminated by a bright green fireball streaking down from the sky — the largest and brightest we’ve ever seen. It moved very slowly through the sky, dropping out of sight below the horizon line. The picture above is not a real photograph (as you’ll quickly be able to tell if you’re familiar with constellations since the star field is just random dots), but is a re-construction made with a photo-editing program so that we could re-capture from our memories the vision of this amazing sight.

If you get clear skies, it might be worth it to brave the cold and sit for awhile, gazing upward. The Orionids are not known for a high volume of falls, but they do have a reputation for producing some spectacular fireballs, and for us, at least, that reputation is well deserved. Happy Viewing!

While others are big enough to stand in –

And others are quite immense –

Many remain unexcavated, and could be sixty feet deep or more! It was interesting to consider the small ponds that had made their homes in the potholes, and it would be a fun project to document the life that calls these ‘pothole ponds’ home.

We also had other adventures at Interstate Park. We rescued a confused and exhausted goose that was running about in a local intersection– with some difficulty we caught it and took it down the riverbank. We also had some great fun climbing the cliffs.

Interstate Park is definitely worth the visit — it boasts the highest concentration of these potholes in the world. We’d recommend a week-day visit if you can, however, as it is VERY popular, and the weekends can be extremely crowded. Do let us know if you pay it a visit!

This is one of the biggies, and tonight and tomorrow night are peak viewing times, the only ‘downer’ being the gibbous moon that will shed a little too much light on the subject.  You can expect to see a lot of falling stars — perhaps up to one a minute — and in the early evening, when the moon is still not interfering, you have a good chance of seeing ‘Earthgrazers’ — meteors that approach from the direction of the horizon, leaving long, bright, colorful trails.  They’re a real treat to see.  Find a good north vantage for prior-to-midnight viewing.  Enjoy!

If you haven’t already, it’s time to go out and see the Delta Aquarids.  They peak at the end of the month, but they’re active now — last evening we saw some great ones.  You’re fine going out any time that the sky is clear, but if you’re serious about things, go out in the wee hours before dawn.  The New Moon right now means that the sky is nice and dark.

Enjoy!

It was only later that we learned that this wasn’t a sundog at all, but rather a phenomenon called a 22 degree halo.  Sundogs are bright points that form on halos.  In fact, there are a whole mess of cool sun- (and sometimes moon-) associated rings, bright spots, and other visual amazements formed by ice crystals in the sky.   Here is a link to some great photos at Wikipedia.

This was an excellent reminder to us that it’s always good to stop throughout the day and look around ourselves.  There’s sure to be something interesting on the ground, over the horizon, or right up above us in the sky!

We were waiting for a special visitor that my brother and his wife had seen just the day before — that famous sucker of sap, the Yellow-Bellied Sapsucker.  But the sapsucker declined to put in an appearance,  so we had to console ourselves with observing the shallow holes the bird had created in the maple’s bark.

The whole affair got us pretty hungry, so after taking some pictures, it was time for our own maple sap feast — this time with highly concentrated maple sap drizzled over pancakes.  I guess we like maple sap too!

But first, just what are falling stars?

Surprisingly, many of them are bits of debris not much larger than grains of sand.  Because they are moving so fast, they create a lot of energy when they hit the Earth’s dense atmosphere, and the result is a bright flash in the sky.  Of course, some meteoroids are much larger, and a few have left immense craters on the Earth’s surface.  The actual piece of debris is called a meteoroid, while the bright flash is called a meteor.  If one hits the ground and survives, it’s called a meteorite.  Sometimes you will get a spectacular fireball - this is when a larger piece of debris enters our atmosphere, sometimes breaking up into pieces (forming multiple trails) and sometimes exploding with enough sound that you can hear it on the surface of the Earth!  Knowing these are out there sort of makes us want to stay up all night every night watching for one!

The great news is that we can mark on our calendars when showers are going to occur, and just stay up all night a few times per year =)

Here are some of the best times in 2009 to see some really good displays--

On the nights of April 21^st and 22^nd, go out to see the Lyrids.  You’ll see some good dust trails that tend to linger for a few seconds.  Sometimes there are ‘bursts’ of up to 100 meteors per hour. It will be a new moon, so the viewing should be good if the clouds stay away.  The best time will be from midnight till dawn, and watch for meteors emerging from the area of the constellation Lyra.

The Eta Aquarids arrive on May 5^th and 6^th.  The best time to see them will be just before sunrise – get up early!  Watch for meteors emerging from the area of the constellation Aquarius, near the y-shaped ‘Water Jar’.

The Delta Aquarids arrive on July 28^th and 29^th.  You’ll see bright, yellow meteors that travel relatively slowly.  Again, get up early, as they favor the hours just before dawn.  Watch for meteors emerging from near the constellation Pegasus.

The Capricornids offer a good chance to see fireballs.  They arrive on July 29^th and 30^th, right after the Delta Aquarids.  They enter our atmosphere slowly, producing bright, long-lasting burns.  Watch for meteors emerging from the area of the constellation Capricorn.

The Perseids, arriving August 12^th, bring a consistently large number of meteors.  Expect to see over 50 per hour!  Unfortunately, we’ll be up against a waning Gibbous moon.  Watch for meteors emerging from the area of the constellation Perseus.

The Orionids come on October 21^st and 22^nd, and since they arrive on a new moon, they could be one of the ‘big ones’ this year.  They don’t produce a high volume of meteors, but the ones you see will often be bright green or yellow in color.  The Orionids are also known for delivering an occasional fireball.  Watch for meteors emerging from the area of the constellation Orion.

The Leonids peak every 33 years – the last peak was in 2001, so we have a wait before they deliver their full glory again, although some astronomers are hinting that we might have an unusually abundant year in 2009.  Get out to watch on November 17^th and 18^th, since there will be a new moon and thus a dark sky.  Watch for meteors emerging from the area of the constellation Leo.  If we do get a meteor storm, this could be a year to remember!  Just before dawn is usually the best time for viewing, but check throughout the night.

The grand finale this year will be the Geminids on the night of December 13^th.  You’ll see multi-colored displays streaking out of the sky – red, blue, green, yellow, and white.  Best of all, it’s a near-new moon, and the sky will be plenty dark.  There will be lots of meteors – this could be a regular falling-star party.  Don’t miss this one!  Watch for meteors emerging from the area of the constellation Gemini.

There are other showers throughout the year, and if you go outside on any clear night and watch for a while, you might get lucky and see a stray fireball.  At the very least, you’ll witness a few swift, bright meteors lighting the sky.  I’ll also be posting reminders before each of these showers.  Have fun viewing!

Note:  The Lyrids are upon us!  You might start seeing increased activity as soon as tomorrow evening!
