hello
i can not say what you are seeing but i think the blinking one just might be a orbiting satellite and the weather makes it seem like it is blinking in and out..
for the last couple of years when i see something like that here..and we have good sky visiblity - no light pollution
well i have to go look up what, if any satellite is tracking across my part of the sky
here are some sites that have good tracking and then just do a search on
satellite tracking..even nasa tells ya where some of them are...
it's kinda amazin how many are up there
