Long Slow Colorful Meteor Last Night- Aquarids? new
      #2543305 - 07/26/08 09:30 PM


To all

While I set up my telescope last night July 25th at 1145 PM PDT with intentions to sketch the waning last quarter moon, instead I witnessed some late fireworks. One of the longest and slowest meteors I have ever seen. It started far to the southeast from the Aquarius or Capricorn region and trailed with a definite orange train, led by a berryllium green fireball that was about equal to Jupiter in brightness as it passed just over the planet across the top of the Teapot of Sagittarius and finally winking out at Antares. It almost outshone the local streetlamps. I sketched a quick pencil sky map and jotted the time down then began the pastel in 9” X 12” format on Artagain paper while fresh in my mind.

Unable to identify other than a sporadic, I found these descriptions in the Meteor Association web site to identify characteristics -Mark >

Recommended for: Early risers who want to brush up on their meteor observing before the Perseid peak.

The South Delta Aquarids are barely a major shower from 40 degrees N. They are part of a complex of radiants in Aquarius, Capricornus and Piscis Austrinus, all of which combine with sporadic and early Perseid activity to provide a nice display of meteors on moonless mornings in late July. The stream normally produces about 5-10 meteors/hour, with overall activity of about 30/hour under good conditions. This year the Full Moon severely restricts observing near the maximum, but a decent number of meteors should be visible a couple of days beforehand.

The South Delta Aquarids are medium-speed meteors, and tend to be faint on average. Meteors from this stream are easily confused with those of several minor showers with nearby radiants. The Piscis Austrinids have a radiant near the bright star Fomalhaut. A weak, diffuse radiant called the "anthelion" or "eclipticids" is also nearby. Farther west is the Alpha Capricornid radiant, which produces slower, often impressive meteors. You may not be able to assign every shower meteor to its correct radiant, but that doesn't mean you can't enjoy the show!

The faintness of most of this activity and the large number of faint sporadics mean that a dark sky is almost essential to the appreciation of this late-July enhancement of meteor rates. The radiants are higher in their sky for southern observers, but the Moon is still a pain. The best viewing window above reflects a short period between moonset and morning twilight.

Mark,

In addition to the beautiful capture of the bright meteor, you captured the heart of the Milky Way, Jupiter, Antares and the teapot in between. Your street lights(too many) are shielded but the city needs to point them straight down. Excellent Drawing.

Wow Mark. That is spectacular! Incorporating the mottled Milky Way, and foreground for context really bring this one home. Great technique.

Frank and Jeremy

Thanks for the compliments- Yes and no as to Franks statement about "too many streetlights". I would counter that with "not enough diplomatic astronomers and/or health and education officials to address the local electric company." I have edited this reply seveal times as I found a link ad it needed updating and if I may beg the moderators to allow me a little latitiude here; I just found this great link to a Wall Street Journal article on light pollution from last Fridays paper with a short 4 miute video from the author>

This is a topic for another discussion perhaps that I have made great strides in with little effort locally where others in the local astronomy club could not. When I built my home 20 years ago under dark skies many miles to the east in the Columbia River Gorge town of Troutdale about 20 miles east of Portland, I had just bought my new 10 inch Coulter Odyssey Dobsonian reflector. I called the local street lighting people and complained of "light trespassing" that was shining into my new homes windows and inhibiting my families sleep. This is a known health issue. I would not have told them that I am an astronomer or they would have not come out to add extra shrouding to contain the ambient and stray street lights. Almost no one else in the local club of hundreds knew how to diplomatically talk to the electric company as they could not get the results that I attained simply over the phone.

I wrote an article for the local astronomy club news letter on this subject. Perhaps I can post it here somewhere in the proper forum. It brings light to this issue (if you’ll excuse the pun) in a biting, cultural and humorous way as you know I always do.

I am very disturbed as to where I must reside temporarily now as I lost my home of 20 years in foreclosure a few months ago. I was in dark skies for nearly 30 years. The home I designed with large vaults and skylights, is a past life now- See it at > www.myspace.com/marksolarprophet (see upper right column area)

I am now residing back in an area, you have to do is you who was once to who who staying with friends where my parents first home was in 1955 as that was the edge of town 7 miles out from downtown Portland in 1955. The old street lights are still here, not like my newer area 25 miles out where I even asked the local lighting authorities to add extra shrouds around the street lights. I could walk out and look up and naked-eye visible the Andromeda Galaxy for 30 years until a few months ago, I lost all that.
Do you
I am now back in the dark ages for lighting- That is to say the bright “cobra head” streetlights that direct light in all directions and the locals here think that that is good for crime. They don’t get it. It is horrible for any possible dark sky astronomy but I can still see the bright things like the planets, moon, fireballs and of course the sun.

I rendered the Milky Way in this sketch as you can barely see it just toward the southern sky but not overhead.

-Mark

Mark,

A beautiful rendering of an interloper of the night. That must have been a very impressive bolide. The colors are very prominent as they tend to be. The Milky Way in the background is a nice touch. Thank you for sharing it with us all.

Carlos
