It's that time of year again.

Remember:

- The shower peak is the night of Aug. 11 through the morning of Aug. 12.

- Shower builds slowly and then falls off a cliff. So some will be seen on evenings and nights before the 11th. So, don't be surprised if you see some tonight!

- Generally, the shower's radiant point is the constellation Perseus. It appears first in the North East sky.

- HOWEVER, best viewing technique is, generally, lay on your back with feet facing North or North East. Then look straight up and let your peripheral vision pick stuff up.

- Goes without saying to be in a dark area, with views horizon to horizon.

- Good viewing usually starts about 9PM on the 11th and peaks about 2AM on the 12th.

- If you have something like a phone with GPS, a compass and something that knows up and down, try a program like Google Sky to know where Perseus is.

- For the Hams, meteor scatter (MS) doesn't care about light and dark, and does quite well until noon-ish on the 12th. The best bands for MS are 10m, 6m and 2m. Most folks go for 2m for the challenge. Others go higher, e.g. 220 and 432, but that's for the experts and not very productive. There's a coordination freq on 75m phone, but I don't recall the frequency. A lot of the serious Ops prearrange their schedules. Minimum equipment on 2m (barring some fancy comm modes) is 150W and 13dBi of antenna.

- For non-Hams with a scanner, you can listen for things like TV or FM stations in places at the right distances. Examples would be all the FM radio stations and TV channels 6 and below. Can easily hear places like Great Falls, MT, Vancouver and even AK. Takes a monster meteor to get a long transmission, but remember, we're talking powerful broadcast stations and the meteors that do this are hundreds of miles from you. Pester Craig. Maybe he can do something with his scanner stream.

- The little streaky meteors are objects the size of a grain of sand. That means they're moving really really fast when they hit the atmosphere. To the hams listening, the most you get out of these are a ping (assuming someone is transmitting where you're listening, etc.).

- The altitude where they burn up is roughly 50 miles (height above earth). That just happens to be about the same height as the E-layer of the ionosphere. Soooo, single hop communication on meteor scatter (MS) is, generally, on the order of 1000-ish miles. What's really cool about this kind of comm is that backscatter happens. When you hear one of those signals, it sounds echo'y. Kinda cool when you hear someone on the other side of the mountains or otherwise out of line of sight, but still closer than typical for MS.

- Also, because of the speed at which these things travel, Doppler effect is obvious on radio/TV signals, especially for the Morse code (CW) operators.

- Meteors that you see to the South are probably "randoms", and not associated with the Perseids.

Lastly, when it comes to meteor activity, we're subject to Mother Nature's whim. The East could have a great shower and the West totally suck. The last few years have been not great for our area, BUT, you NEVER know, so watch anyway.

I'm writing this in a hurry, and I'm sure I forgot something. So, if interested, keep an eye on it and I'll edit if I think of anything.

The old mine above the dump is the first place that comes to mind.

Anything that overlooks the desert risks a lot of skyglow, even to the East.

Don't forget that most of the meteor trails will originate toward the North and East, so better to be on the North side of the Valley.

Also don't forget that far out in the desert could be excellent viewing.

If you choose a bowl-like area, try to keep the rim sight line below 20 degrees elevation.

I forgot all about the meteor shower. But I heard the horses making a fuss so got up in the wee hours of Monday morning- about 2AM. Looked out the window in time to see a LONG trail going from south to north!! THEN I remembered the shower!! Guess it was just lucky timing!

So Far as of 9pm. no quakes felt in the Indio area by myself. My cell phone goes off a lot with each new quake, so I am aware of them constantly thou.

Should move the forest closed sign again? They just move it back. Haha.
I have a plethora of giant (3-6 footers) granite boulders I could tractor down, if I had an opening dimension and permission. Hehe, too much work.. and none of my business anyway.

Rocks for sale?
