Hi @donheff ,
thank you for your message. Well, sometimes the answer might be "it depends" 🙂
On a basic level, the scheduler on every observatory orders the requests according to their age, i.e. the older have precedence on the newer. However, this sorting is done after having evaluated all constraints of all currently scheduled requests.
So, some are excluded due to moon distance. Some are excluded due to being (still) too low. And whatever remains is sorted and the first is taken for imaging.
Now, in the last couple of days another two issues are ruining the party: First (and foremost) the weather, as the rainy season is approaching we are basically stopped due to bad weather. Also, three days ago we had a power outage which stoppe dthe H8 and Samyang completely in the late evening.
Also, the Samyang is still a bit of a mistery to get it going correctly. It hit once again the roof, and I do have to assess any issues that caused. But foremost we are now implementing a safety switch to avoid such contact in the future 🙂
Will keep you posted 🙂
