Astronomical works by P.A.Semi
- Orbital Resonance and Solar Cycles,
was published initially here on Gurroa.cz at 2009, March 27, on the
occasion of heliocentric conjunction of Earth and Venus planets...
(updated version as of 2010-01-08)
Ephemerides program, used to calculate the charts in this work, can be downloaded
at EphView sub-directory...
- Periodicities in the Solar system
(current draft, 2010-03-24)
The Supplement (27Mb in ZIP format) includes
some images from the paper in PNG format and data-files in XML format for my EphView program
(which could also be used just as a plain-text format, separated by " (quote) character, take 2nd and 4th column as date and value...).
- Musical analysis of planet intervals (current draft, 2010-01-05)
- PLANETARY TIDAL EFFECTS ON SOLAR ACTIVITY - I have been a co-author of
this work for a conference in Petrograd. There are some mis-spellings in my part of the work:
I am terribly sorry, that I did not find a time for correcture: the SSB was displayed on images
but was obviously not used in tidal calculations...
- Architecture of the Solar System
and Earth placement into livable zone arround its Star (current draft, 2012-06-06, published
on occasion of Earth-Venus heliocentric conjunction).
This paper also describes the cause of the Sunspot cycle - magnetic linking of planet Earth and Sun,
by tuning of the Moon orbit with the Solar spin... (This second part is very probably an error!)
- Interpolated Sunspot area and Synoptic Sunspot Map
1874-2012, north-south asymmetry. (PDF)
By interpolating far-side Sunspots,
the false 27-day signal is almost removed, so that the Sunspot record can be explored without
23 Mb for download, data-files and program to generate 3.5Gb of PNG files
with Sunspot maps (1-2 hours of runtime needed to generate), spanning years 1874-2012,
with the basic charted data already included...
Connection with Earth-Venus-Jupiter syzigy and quadratures is shown on an included chart...
- Chandler wobble
and LoD variation. Analysis and some prediction. (2015-06-11)
- Solar surface flow in SC24
(2017-06-19, updated 2018-06-22)
- HMIB/AIA171 mix - browse images... (experimental) (2020-03-03)
Topology of the curved space-time universe,
which refutes "Big Bang" theory and confirms Einstein's universe
shape of universe as a 3D surface of a 4D hyper-sphere,
based on Curvature cosmology of David Crawford,
modifying it's explanation of stability of this solution
and drawing some interesting consequences.
Second part of this work explains gravity acceleration
as a negative centrifugal force due to movement in time with imaginary speed ic.

David (Bethlehem) star
explained as an astrological phenomenon,
dating birth of Jesus Christ to winter 3BC (year -2 if 0 was in middle)
2012-06-06 Venus in front of the Sun
(Venus was 3.5x more near to us)
