Although the SGC has been using the Beta Stargate discovered in Antarctica since Small Victories (2000), the point of origin of the Alpha Stargate is clearly visible, as opposed to the point of origin of the Beta Stargate that was previously seen in Solitudes (1998).
At 15:34 in the infirmary, Teal'c gets a thermometer inserted in his mouth. A few seconds later on the close up the thermometer isn't there and gets re-inserted. However, he is reluctant to have the device in his mouth and removed it off-screen.
When O'Neill touches Daniel's monitor to open a picture, the second button O'Neill presses (one of many) is flashing as soon as the menu opens as if it had already been pressed, well before O'Neill touches it.
When Teal'c has the thermometer in his mouth, it is obviously on top of his tongue, not under it.
During the briefing about setting up the remote observatory, Jack displays ignorance of Carter's plans to observe the coronal mass ejection. It was established from the first episode of Stargate SG-1 that Jack is a keen amateur astronomer; the airmen who came to his home to take him to the Stargate HQ found him on his roof using a telescope. It is therefore unlikely that Jack would not have knowledge of or display indifference towards an astronomical event such as a coronal mass ejection.
While playing golf through an active Stargate, Jack asks Teal'c how far away the planet on the other end is; Teal'c says "several billion miles." Given that one light-year is approximately 6 trillion miles, and the closest star-system is 4.5 light-years from Sol, Teal'c is off by several orders of magnitude. This is mostly likely due to Teal'c having no working knowledge of astronomy and so he was probably unaware of the true scale of interstellar distances.
