Eclipse Season is Approaching for SDO! | |
Dr. Deplorable Astromut Senior Forum Moderator  01/09/2019 12:20 AM  Report Abusive Post Report Copyright Violation | Twice a year the Solar Dynamics Observatory spends a few weeks passing into earth's shadow for a period of time each day, blocking out the sun. Some claim that these events are abnormal and that the eclipse explanation is just a cover up. To address this, I conducted my own observations of the SDO spacecraft this morning with my telescope, and used that data to calculate its orbit. I then generated prediction videos for every eclipse in the upcoming eclipse season based solely off of my own orbital data. If it's caused by something other than passing into earth's shadow, there is no way my prediction should come true. The first eclipse is predicted to occur on February 6th according to my data and my software, less than a month from now. I used the orbit I calculated to generate predictions for every eclipse in the coming season and these videos are located in the Annotated SDO bot channel I've set up to automatically run these predictions.

The reason the left wants you disarmed is because they plan to do things to you that you would shoot them for. To a cat, "No" just means to try again later. Silver kills disease organisms and also cures banksteritis. |

| Dr. Deplorable Astromut (OP) Senior Forum Moderator 01/09/2019 11:25 PM Report Abusive Post Report Copyright Violation | How many satellites will suffer blackouts during SDO? I know living in the tropics, it's not too uncommon better 10am-2pm to experience temporary outages due to solar interference. Quoting: Agent MIB SDO is in an inclined orbit, so it's geosynchronous rather than geostationary. As a result the eclipse season it experiences does not necessarily coincide with the eclipse season experienced by geostationary satellites. For geostationary satellites eclipse season is pretty much the same from year to year for a given location. Think of it like this, the orbit of sdo travels north and south of the equator by up to about 29 degrees. That means the sun earth and spacecraft can be lined up at times of the year that are distant from the equinox. Because the orbit gradually changes over time and the timing of when it crosses the ascending node of the orbit changes over time, so the eclipse season itself will change over time from year to year. This doesn't apply to geostationary satellites whose orbits are always at 0 degrees inclination and effectively have no ascending node (the point in the orbit where it crosses the equator heading north). |

Thanks for clearing that up for me. I always thought the SDO's were at Earth's Lagrange points ahead and behind the Earth's orbit. At my age, I call it having a "senior moment" when I forget things.
