Notes about occultations:The timing is very specific to your exact location. Few clocks can be relied on to be accurate at the sub-second level, including the cheap radio-controlled clocks which are typically corrected once per day around midnight. Also, it is very difficult to visually determine the exact time when a star appears or disappears at the illuminated limb of the moon. Photography, therefore, is very helpful. No lunar occultations of a bright star will be visible this year from Rapid City.
We might think that astronomy reports on the web could be relied on, but then counter examples do show up. Here are a couple of them.https://www.livescience.com/64433-milky-way-large-magellanic-cloud-collision-imminent.html
No, the universe isn't going to kill us tomorrow - although some of the information in this article is based on computer simulations, the theory on black holes seems to be speculative. The article also seems to have barely hidden humor in it with the suggestion that we should set our doomsday clocks for 2 or 3 billion years in the future.

WEEKEND SOLAR ECLIPSE:On Sunday, Jan. 6th, the Moon passed in front of the sun, off center, producing a partial solar eclipse visible from coastal China to the Aleutian Islands of Alaska. During the event, as much as 71% of the solar disk was covered. Browse the solar eclipse gallery for photos.
The eclipse covered up to 71% of the sun's diameter, but only up to 62% of the sun's disk by area. The "71%" figure relates to the "magnitude" of the eclipse, not the obscuration. Shame on Spaceweather.com for going in for hype, or using sloppy terminology.
