I took these 3 pictures of the same satellite (CAS4A) at close to the same time so as to illustrate my confusion. So let me see if I can post them in some sort of order. I live in Houston TX.
ScreenShot(SS) #1 If you look at the 1st line it says that the bird will start at 5:49:24, then not again until tomorrow. This seems to conflict with SS#2 which says Start Azimuth at JUN 30, 07:56. Why are they different and SS #2 and #3 look to me to show it visible and reachable.
#1 and #2 are from N2YO.com. #3 is from Heavens Above. GOSATWATCH on my IPhone agrees with Heavens Above.
Are the TLE numbers updated frequently ? When ?

hextejas, it almost looks like you used the "Insert link (Ctrl+K)" function rather than the "Insert image (Ctrl+P)" function. I say that because when I click on the graphic by your filename, Radio Reference responds with "The requested page could not be found." Since it appears to be trying to pull a webpage, that is why I'm thinking you may have used the "Insert link" function. Please try again using "Ctrl+P" as a shortcut.

One of your images still isn't showing.

But judging by the times, it appears that the heavens above ground track is a pass that has already occured, and the N2YO image is the actual next pass.

I'm assuming that the one image that is not showing is a list of passes that does not show the pass shown in the N2YO image. My guess is that that list doesn't show passes below a certain elevation, and the 12 degree actual next pass doesn't pass through that filter.
