Find the Perseid

Post by RJN » Tue Aug 10, 2004 7:12 pm

Our first entry in the "find the perseid" contest is this frame:
Image
taken August 9 from Mauna Kea. The streak at the top (hard to see?) may be a Perseid meteor, although we cannot say for sure that it was not an Iridium satellite flare.

The blurry part in the image center is probably due to water that leaked into the lens and is slow in evaporating.

Please feel free to post here images of (probably) Perseid meteors over the next few days. The Perseids peak on August 11 and 12.

Here is another one

This is a much clearer one with a longer tail coming directly from Pereseus, captured by a 20 second exposure frame (what makes it possibly fainter?)

Unlike the one above, examining the fits frame shows that this one flashes first, and than continues while gradualy vanishing. The previous one gets gradually brighter, then flashes, and then gets dimmer.

Yeah, the current Mauna Kea animation shows that last Perseid very well. Very cool (although I'm hoping for no clouds tonight, personally).

Here's another near the top of the frame:

I noticed it by eye and "confirmed it" by blinking it in my browser with the next image taken.

Another nice one in the Canary Islands:

Curious about a blip from a few slides later, however. There's a "scratch" immediately "SE" of the W designator (3pm position) in this slide:

Image

Now this scratch clearly does not come from the same radiant as the Perseid noted in the other slide. Is this a defect, a non-Perseid meteor, or something else entirely?

Gah, I can answer this myself. They're both Perseids, its just that I need to wrap my walnut-sized brain around the concept of the radiant and a fish-eye lens. Upon a bit more reflection I've convinced myself they're both coming from Perseus.

Near the bottom slightly right of center.

I'm somewhat surprised the transient detection isn't picking these up.

Mauna Kea has recorded many persieds in the past few hours. Here is a real bright one:

If one plays this 10-frame movie (automatically generated by NSL's numbercruncher for last 10 frames), one can see at least three really bright Perseid meteors flash!

Odd as it sounds, I think I spotted one from Siding Spring.

Take a look at the far upper right, next to Bootes. It's easier to see on the movie.
