|

Fri Nov 20 23:03:34 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to v1.33
|
||
* Fix: running ``load.timescale(builtin=False)`` was raising an
|
||
exception ``FileNotFoundError`` if the ``finals2000A.all`` file was
|
||
not already on disk, instead of downloading the file automatically.
|
||
`#477 <https://github.com/skyfielders/python-skyfield/issues/477>`_
|
||
- v1.32
|
||
* A new :func:`~skyfield.eclipselib.lunar_eclipses()` routine finds
|
||
lunar eclipses and determines their degree of totality.
|
||
`#445 <https://github.com/skyfielders/python-skyfield/issues/445>`_
|
||
* The almanac module’s new :func:`~skyfield.almanac.meridian_transits()`
|
||
routine can find the moments at which a body transits the meridian and
|
||
antimeridian.
|
||
`#460 <https://github.com/skyfielders/python-skyfield/issues/460>`_
|
||
* Fix: the :func:`~skyfield.searchlib.find_minima()` function was
|
||
ignoring its ``epsilon`` and ``num`` arguments and always using the
|
||
default values instead.
|
||
`#475 <https://github.com/skyfielders/python-skyfield/pull/475>`_
|
||
|
||
* Fix: the ``.epoch`` attribute of Earth satellite objects that were
|
||
built using :meth:`~skyfield.sgp4lib.EarthSatellite.from_satrec()`
|
||
was, alas, a half-day off.
|
||
`#466 <https://github.com/skyfielders/python-skyfield/issues/466>`_
|
||
|
||
* Fix: the :class:`~skyfield.toposlib.Topos` constructor arguments ``x``
|
||
and ``y``, which never worked properly, have been deprecated and are
|
||
now ignored.
|
||
|
||
1.31 — 2020 October 24
|
||
----------------------
|
||
|
||
* Skyfield now uses the International Earth Rotation Service (IERS) file
|
||
``finals2000A.all`` for updated ∆T and leap seconds. The USNO is no
|
||
longer updating the files ``deltat.data`` and ``deltat.preds`` that
|
||
previous versions of Skyfield used, and the ``cddis.nasa.gov`` server
|
||
from which they were fetched will discontinue anonymous FTP on 2020
|
||
October 31. See `downloading-timescale-files`.
|
||
`#452 <https://github.com/skyfielders/python-skyfield/issues/452>`_
|
||
`#464 <https://github.com/skyfielders/python-skyfield/issues/464>`_
|
||
|
||
* The comets dataframe built from the MPC file ``CometEls.txt`` now
|
||
includes the ``reference`` column, so users can tell which orbit is
|
||
most recent if there are several orbits for a single comet. (For
|
||
example, the file currently lists two C/2020 F3 (NEOWISE) orbits.)
|
||
The comet examples in the documentation now build a dataframe that
|
||
only includes the most recent orbit for each comet.
|
||
`#463 <https://github.com/skyfielders/python-skyfield/issues/463>`_
|
||
|
||
* Two new methods :meth:`~skyfield.iokit.Loader.days_old()` and
|
||
:meth:`~skyfield.iokit.Loader.download()` make it simple to download a
|
||
fresh copy of a file if the copy on disk is older than you would like.
|
||
|
||
1.30 — 2020 October 11
|
||
----------------------
|
||
|
||
* The various ``strftime()`` Skyfield methods now support the ``%j``
|
||
day-of-year format code.
|
||
|
||
* Fix: the new Julian calendar support broke support for out-of-range
|
||
month numbers, wrapping them into the current year instead of letting
|
||
them overflow into subsequent years.
|
||
`#461 <https://github.com/skyfielders/python-skyfield/issues/461>`_
|
||
|
||
* Fix: a stray debugging ``print()`` statement was stranded in ``t.dut1``.
|
||
`#455 <https://github.com/skyfielders/python-skyfield/issues/455>`_
|
||
|
||
* The :class:`~skyfield.timelib.Time` object, if manually instantiated
|
||
without a Julian date fraction, now provides a fraction array with
|
||
dimensions that match the Julian date argument.
|
||
`#458 <https://github.com/skyfielders/python-skyfield/issues/458>`_

Sat Sep 26 08:13:08 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.29
|
||
* Fix: the new Julian calendar feature was raising an
|
||
exception in the calendar methods like
|
||
`skyfield.timelib.Time.tt_calendar()` if the time
|
||
object was in fact an array of times. #450
|
||
* Fix: trying to iterate over a time object would raise an
|
||
exception if the time was created through
|
||
`~skyfield.timelib.Timescale.ut1()`.
|
||
- Version 1.28
|
||
* Broken URL: Because the VizieR archive apparently decided
|
||
to uncompress their copy of the hip_main.dat.gz Hipparcos
|
||
catalog file, the old URL now returns a 404 error. As an
|
||
emergency fix, this version of Skyfield switches to their
|
||
uncompressed hip_main.dat. Hopefully they don’t compress
|
||
it again and break the new URL! A more permanent solution
|
||
is discussed at: #454
|
||
* To unblock this release, removed a few deprecated pre-1.0
|
||
experiments from April 2015 in skyfield.hipparcos and
|
||
skyfield.named_stars that broke because the Hipparcos
|
||
catalog is no longer compressed; hopefully no one was
|
||
using them.
|
||
* In a sweeping internal change, the
|
||
`~skyfield.timelib.Timescale` and
|
||
`~skyfield.timelib.Time` objects now offer support
|
||
for the Julian calendar that’s used by historians for
|
||
dates preceding the adoption of the Gregorian calendar in
|
||
1582. See choice of calendars if you want to turn on
|
||
Julian dates in your application. #450
|
||
|
||
-------------------------------------------------------------------
|
||
Wed Sep 16 09:53:08 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.27
|
||
* The printed appearance of both vectors and of vector
|
||
functions like Earth locations and Earth satellites
|
||
have been rewritten to be more informative and
|
||
consistent.
|
||
* Added compute_calendar_date() which lets the caller
|
||
choose the Julian calendar for ancient dates instead of
|
||
always using the proleptic Gregorian calendar. This
|
||
should be particularly useful for historians.
|
||
* Added J() that builds a time array from an array of
|
||
floating point years. #436
|
||
* Added four new strftime methods for the non-UTC
|
||
timescales (#443). All four of them support %f for
|
||
microseconds, and provide a reasonable default format
|
||
string for callers who don’t wish to concoct their own:
|
||
tai_strftime()
|
||
tt_strftime()
|
||
tdb_strftime()
|
||
ut1_strftime()
|
||
* Thanks to several fixes, comets and asteroids with
|
||
parabolic and hyperbolic orbits should now raise fewer
|
||
errors.
|
||
* The prototype planetary_magnitude() can now return
|
||
magnitudes for Uranus without raising an exception. The
|
||
routine does not yet take into account whether the
|
||
observer is facing the equator or poles of Uranus, so
|
||
the magnitude predicted for the planet will only be
|
||
accurate to within about 0.1 magnitudes.

|
||
|
||
- Update assay to commit 256.23c18c2 in order to fix non x86 builds
|
||
|
||
-------------------------------------------------------------------
|
||
Sun Aug 2 11:51:04 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.26
|
||
* The official ∆T files on NASA’s FTP server have stopped receiving
|
||
updates — they have no new data beyond February, the start of the
|
||
global pandemic. Unless they are updated by next February, older
|
||
versions of Skyfield will unfortunately download the files all over
|
||
again every time `skyfield.iokit.Loader.timescale()` is called
|
||
(unless the ``builtin=True`` parameter is provided). To make Skyfield
|
||
less fragile going forward:
|
||
1. The loader’s `skyfield.iokit.Loader.timescale()` method now
|
||
defaults to ``builtin=True``, telling it to use the ∆T and leap
|
||
second files that ship with Skyfield internally. To download new
|
||
∆T files from NASA and the leap second file from the International
|
||
Earth Rotation Service, specify ``builtin=False``.
|
||
2. The concept of an “expired” file has been removed from ``load()``.
|
||
Skyfield is now much simpler: if a file with the correct name
|
||
exists, Skyfield uses it. See `downloading-timescale-files`
|
||
if you still want your application to check the age of your
|
||
timescale files and automatically download new ones.
|
||
* The `ICRF.separation_from()` method now officially supports the
|
||
combination of an array of positions with a single reference position!
|
||
Its previous support for that combination was, alas, accidental, and
|
||
was broken with the 1.23 release.
|
||
`#414 <https://github.com/skyfielders/python-skyfield/issues/414>`
|
||
`#424 <https://github.com/skyfielders/python-skyfield/issues/424>`
|
||
* A prototype `skyfield.magnitudelib.planetary_magnitude()`
|
||
routine has been added with support for several planets.
|
||
`#210 <https://github.com/skyfielders/python-skyfield/issues/210>`
|
||
* The ``utc`` timezone that Skyfield returns in Python datetimes is now
|
||
either the Python Standard Library’s own UTC object, if it supplies
|
||
one, or else is defined by Skyfield itself. Skyfield no longer
|
||
silently tries importing the whole ``pytz`` package merely to use its
|
||
UTC object — which also means that the timezone returned by Skyfield
|
||
longer offers the non-standard ``localize()`` method.

||

||
Sat Jul 25 11:43:28 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to version 1.25
|
||
* Added skyfield.data.stellarium.parse_constellations()
|
||
and skyfield.data.stellarium.parse_star_names()
|
||
to load Stellarium star names and constellation lines.
|
||
Constellation lines are featured in a new example script
|
||
neowise-chart that produces a finder chart for
|
||
comet C/2020 F3 NEOWISE.
|
||
* The Hipparcos star catalog should now load faster, having
|
||
switched behind the scenes to a higher performance Pandas
|
||
import routine.
|
||
* Fixed the ability of skyfield.timelib.Timescale.utc()
|
||
to accept a Python datetime.date object as its argument.
|
||
#409
|
||
* Slightly lowered the precision of two tests when they
|
||
detect that Python is compiled for a 32-bit processor, so
|
||
the test suite can succeed when contributors package
|
||
Skyfield for 32-bit Linux. #411
|
||
- use upstreams custom test runner 'assay'
|
||
* The runner does not have any releases yet. No package
|
||
available, so use assay-master-252.79f5d78.tar.gz directly
|
||
* drop skyfield-pr405-replace-assay-by-pytest.patch
|
||
* gh#brandon-rhodes/assay#6, gh#skyfielders/python-skyfield#405
|
||
- the unit test expect a truncated hipparcos catalog
|
||
* generate-hipparcos.sh
|
||
* hip_main.dat.gz
|
||
- drop skyfield-pr404-comparefloat.patch addressed upstream

-------------------------------------------------------------------
|
||
Wed Jul 22 14:13:46 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to Version 1.24
|
||
* Added methods :meth:`~skyfield.timelib.Timescale.from_datetime()`
|
||
and :meth:`~skyfield.timelib.Timescale.from_datetimes()` to
|
||
the :class:`~skyfield.timelib.Timescale` class, to
|
||
better advertise the ability to build a Skyfield time
|
||
from a Python datetime — an ability that was previously
|
||
overloaded into the year parameter of the
|
||
:meth:`~skyfield.timelib.Timescale.utc()` method (where
|
||
it is still supported for backwards compatibility, but
|
||
no longer documented).
|
||
* Fix: improved the accuracy with which velocity is
|
||
converted between the Earth-fixed ITRF frame that rotates
|
||
with the Earth and the inertial GCRS frame that does not.
|
||
In particular, this should make Earth satellite
|
||
velocities more accurate.
|
||
- rebase patches skyfield-pr404-comparefloat.patch
|
||
and skyfield-pr405-replace-assay-by-pytest.patch

-------------------------------------------------------------------
|
||
Fri Jul 10 14:51:52 UTC 2020 - Benjamin Greiner <code@bnavigator.de>
|
||
|
||
- Update to Version 1.23
|
||
* Added `kepler-orbits` support for generating the positions of comets and
|
||
asteroids from Minor Planet Center data files.
|
||
* Added `skyfield.positionlib.ICRF.is_behind_earth()` to determine whether a
|
||
celestial object is blocked from an Earth satellite’s view by the Earth
|
||
itself.
|
||
* Replaced the awkward and hard-to-explain rough_period search parameter with
|
||
the conceptually simpler step_days parameter, and updated the instructions
|
||
in `searches` to match.
|
||
* Made the `skyfield.iokit.Loader.load.tle_file()` import method less strict
|
||
about Earth satellite names: any text on the line before two lines of TLE
|
||
data is now saved as the satellite name. A parameter skip_names=True turns
|
||
this off if, for particular TLE files, this leads to unwanted text being
|
||
saved
|
||
- directly copy downloaded testfiles as sources
|
||
- move skyfield-openSUSE-comparefloat.patch to skyfield-PR404-comparefloat.patch
|
||
and submit upstream: gh#skyfielders/python-skyfield#404
|
||
- move skyfield-openSUSE-replace-testrunner.patch to
|
||
skyfield-PR405-replace-assay-by-pytest.patch and submit upstream:
|
||
gh#skyfielders/python-skyfield#405
|
