SwiftAA, the most comprehensive collection of accurate astronomical algorithms just reached v2.0! This is the first version of complete Solar System APIs with units safety and a whopping 90%+ of unit tests coverage.
I am very proud of the result. Lots of things remain in the pipe for an even more amazing v3, but here you have: a complete set of easy-to-read and documented APIs to compute everything you need about the solar system.
It’s been a while now that I chose to make my app iObserve free for all (both on macOS and iPad) and to support it at the basic level (I know iObserve on iPad hasn’t received yet the update it deserves). If you don’t know why, you should read this.
But of course, it keeps thriving! And a lot of people use it! And one of the best channel I have to get a sense of how often it’s being used is the mails I receive to include new builtin observatories. Check this out only for this summer:
It is really warm feeling to see this.
But if you follow this blog, you also know that I am developing arcsecond,io and that it has a dedicated observatories page, right?
Of course, the obvious thing to do is to plug arcsecond.io into iObserve to make it easier for everyone to contribute! And this is what I planned in the past to do, but in the v2.0 of iObserve… which is stalled, because I develop arcsecond.io. Arg!
Enough cheating. This blog post is to announce I will develop an update of iObserve 1.6 to use the observatories in arcsecond.io. That is, I will not wait for v2 of iObserve. The tricky part is that the ObservatoryManager is something essential of the app, and I can’t develop this overnight. But enough said, and back to work!
Collaborative work help great developers to push their own ideas forward. Alexander Vasenin participated to key improvements of SwiftAA, put in place by yours truly. SwiftAA, based itself on AA+ by PJ Naughter, but with much easier and swifty APIs, is the most comprehensive and accurate collection of astronomical algorithms in Swift (and Objective-C along the way).
Alexander just released a wonderful and very detailed iOS app about meteors, called MeteorActive. Find everything about these beautiful phenomena in a snap, thanks to this carefully crafted app. And it’s free!
I may not update this blog very often, but things keep moving forward!
First, I’ve fixed an important bug in SwiftAA, the iOS/macOS framework of astronomical algorithms. There was a confusion on ecliptic coordinates, which was then propagating to other coordinates, and making impossible to have reliable times of Rise, Transit and Set for celestial objects. What a pity if you couldn’t compute these times with SwiftAA! It is now fixed. Check the release. Even if it takes time, I keep moving forward to reach the 2.0 milestone.
The other updates are about arcsecond.io. I made progresses in many compartments: Datasets, Night Logs, Observing Runs, Profiles. Objects page, Publications etc etc. The new root page now has a Google-like search field. For the exoplanets side, I’m working on something very cool, but it isn’t ready yet (planned for v0.3).
You can check the changes and the improvements brought by every release in the dedicated Changelog page.
As for iObserve, I keep receiving new observatories. Thanks to all. I may consider an update of iObserve to use observatories in arcsecond.io once back from vacations. Better not promise anything though, I know how it goes…
But here is something I am busy with right now: Observing Runs, for which I needed Observing Sites. Looks like a online version of iObserve…
A very first selection of an observing site inside the Observing Runs dashboard.
I know, I am building again a 3-columns-with-topbar layout… But I think this is clearly the most adapted to a pro app like that. More to come soon!
Coming very soon, a brand new observing sites page! Stay tuned.
