(meteorobs) Swift Sees 5th Magn. GRB!

[stange34 at sbcglobal.net]

Thanks Wayne, I realized my error but could not edit my post.

Because I set handyavi extremely high in brightness & contrast (contrast, is 
set to 6533, brightness is set to 5400), with normal being 5000 for both, 
it should have seen a stationary 5th mag light burst.

Darn' airplane traffic caused me to delay turning it on & I forgot it.

YCS
