Dr. John Barentine FRAS<p>Last night I saw the <a href="https://astrodon.social/tags/SpaceX" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SpaceX</span></a> Falcon 9 second stage de-orbit burn and 'ionospheric hole' from the Starlink 12-10 launch out of Canaveral at 0234 UTC. These phone-camera images were made north of Tucson at 0405/0408Z looking northwest and east, respectively. </p><p>My group wasn't aware of the <a href="https://astrodon.social/tags/launch" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>launch</span></a> and didn't initially realize what the de-orbit burn was, thinking it might be a launch out of Vandenburg. But it was in the wrong part of the sky. The duration is only maybe ten seconds, and the blob of light is a couple of degrees in size.</p><p>The ionospheric hole is a shorter phenomenon, lasting somewhat less than 5 seconds. Under moderately dark skies, it was *distinctly* red to the unaided eye, comparable in intensity to a moderate aurora. It faded out from center to edges, perhaps 3° or so in apparent extent.</p><p>To cap it all off, we saw the train of <a href="https://astrodon.social/tags/Starlink" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Starlink</span></a> objects from the prior night's launch (12-23) fly over at 0344Z.</p><p><a href="https://astrodon.social/tags/Space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Space</span></a> <a href="https://astrodon.social/tags/Satellites" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Satellites</span></a> <a href="https://astrodon.social/tags/Ionosphere" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Ionosphere</span></a> <a href="https://astrodon.social/tags/IonosphericHole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>IonosphericHole</span></a></p>
