Fixed in 10.3.1


In the documentation of StarData, there is an example that shows how to get the altitude of Sirius at a given time (in the horizontal coordinate system).

However, when I try to run the example code

StarData["Sirius", 
 EntityProperty["Star", 
  "Altitude", {"Date" -> DateObject[{2014, 4, 9, 22, 0, 0}]}]]

the result is

Missing["NotAvailable"]

Additionally, if I run

StarData["Sirius", EntityProperty["Star", #]] & /@ {"Altitude", 
  "Azimuth"}
StarData["Sirius", 
   EntityProperty["Star", #, {"Date" -> Now}]] & /@ {"Altitude", 
  "Azimuth"}

I get the correct output for the first command and

{Missing["NotAvailable"], Missing["NotAvailable"]}

for the second, which is very strange. Is this a bug with the EntityProperty function?

    $\begingroup$ It appears there was a server-side change that's causing this to fail when it shouldn't. I've notified the wolfram developers about this issue, and hopefully it will be fixed soon. $\endgroup$ – Nick Lariviere Apr 3 '15 at 16:34

    $\begingroup$ The astronomical curated data functions seem to be working normally with the current versions. Can somebody else confirm this? $\endgroup$ – J. M. is computer-less May 31 '16 at 9:49
  • $\begingroup$ @J.M. I can confirm it works in 10.4.0. Thanks for the heads up. $\endgroup$ – shrx May 31 '16 at 10:01

This bug appears to be fixed as early as of version 10.3.1.
