Open Comments Thread

As an experiment, I thought I’d set up an open comments thread for your suggestions or general comments or whatever, and which may include offtopic material as well, so we shall see what happens …. over to you!

Note: the problem with the spam filter that was stopping some posting here has been fixed -however it also told a lie by telling people their comments were awaiting moderation, but it did not put them in the moderation cue, so for anyone that did encounter this problem, unfortunately the stopped comments are nowhere to be found. I apologise for any inconvenience, and plead that being new to blog admin, I am still learning how the various blog controls operate and interact with each other!

If anyone has any further problems, contact me by emailing:

– written to avoid spam – most of you know what to do!

Newcomers: copy the email address above and paste it in the To: field of your email program, replace the AT part with @ and both cases of DOT with . and remove all blank spaces.

  1. Your blog makes a lot of sense and ties in very well with the statements of a Professor Brown from Birmingham University, who visiting Carnarvon Western Australia for a number of years.

    He had 8 solar observatories around the world – a bit Heath Robinson-ish in appearance, but he found that his measurements of the sun’s potassium molecule temperatures produced a number of ranges of waves that closely matched many of the periodic waves that have been mentioned on your blog.

    I will continue to monitor your site with great interest, although most of my physics knowledge is more aligned to my work in Medical Imaging, my interest in and knowledge of the weather has been re-invigorated from reading your information.

    I saw this mentioned on CA recently and don’t know if you picked up on it or were aware of this.

    When I first saw this some time ago, I had an AHA! moment. It appears that the thinking is simmilar Landscheidt’s – but rather than focusing on the effect on the sun of all the planets as Landscheidt did, focuses solely on the effect of Jupiter.

    The predictions are actually quite simmilar – but in this work rely on some weird cycles. Given that Jupiter is more than 50% of the mass of the solar system, plus the fact that it is the closest of the giants to the sun, it may be that these weird cycles are better explained if the mass of the rest of the solar system is taken into account.

    If nothing else, it may give you an idea of methodology if you want to expand on Landscheidt. Food for thought.

    cheers

  3. Dear Carl,
    first of all, my congratulation to your new blogsite, concerning Dr. Theodor Landscheidt’s lifework.To continue his studies, we should take the next step from the correlations, he found, to the physical causes, which influence the sun and the earth, starting from the values of orbit-angular momentum L, which we have the pleasure,to take your new file from this site and calculate the energies from L and angular velocities omega.
    I am looking for partner (s), to do this for the different cycles, which exist in the timescale of L. Naturely, we have to look, for a transfer from values of the orbit to those of the spin of the objects.
    Enough for today, looking, if the posting works and if there is interest of yours or others.
    Best regards

  4. Thanks for contributing Erhard.

    As I mentioned in an email to you, I am looking for the direction and speed of the Solar System within the galaxy so that this can be taken into account in studies of angular momentum and torque.

    In spite of much searching, an accurate direction and speed has so far eluded me, so I have posted a question in the BAUT forum in the hope of getting a useful answer.

    Carl.

  5. Dear Carl,
    so I believe, we have problems in exchanging e-mails, I will give you numbers, you are looking for our solar-system SS in moving in our galaxis G:
    The direction of CM_SS to the center of G is 266.4°, the velocity in direction of rotation: 5.23.10^4 m/s, the velocity towards the center of G: 10.10^4 and the distance to center: 2.4.10^20 m. And so the massspecific (that means for 1 kg) angular momentum L_SSinG is: 1.3.10^25. With an L_SS: 1.6.10^13 the former is 2.10^12 higher.
    I think, we could not handle those even uncertain numbers usefull and therefore we should consider the SS as an closed system. So there is enough to do.
    You can delete these informations if you like, because there is no direct connection to the theme of your blog.
    Kind regards
    Erhard

  6. Hi Erhard, I will leave your comment as it is relevant to what we are discussing.

    My initial intent in setting up the blog was a ‘one-stop-shop’ where Dr Landscheidt’s work could be accessed and discussed, however part of that is also to explore things arising from his work, even if that takes things in other directions at times.

    I now have some more information thanks to my post on BAUT that can be used for what I want to do, which is to rotate the coordinates into the frame of the Sun’s motion through the galaxy, as I see that as another piece of the puzzle that needs to be accounted for in any quantitative approach.

    What I was looking for was the coordinates of the “solar apex” to accomplish this – it took me a while as that particular term had slipped my mind, which shows my memory must be starting to deteriorate with age – it was many years ago now that I intensively studied astronomy!

    Solar Apex Details:

    Source: Wikipedia:

    The general direction of the solar apex is southwest of the star Vega near the constellation of Hercules. There are several coordinates for the solar apex. The visual coordinates (as obtained by visual observation of the apparent motion) is right ascension (RA) 18h 28m 0s and declination (dec) of 30° North (in galactic coordinates: 56.24° longitude, 22.54° latitude). The radioastronomical position is RA 18h 03m 50.2s and dec 30° 0′ 16.8″ (galactic coordinates: 58.87° longitude, 17.72° latitude).
    The stars in the Galaxy’s disk orbit around the Galactic Center. It would take the solar system about 226 million years to complete one orbit (“galactic year”), and so is thought to have completed about 25 orbits during its lifetime. The orbital speed is 217 km/s, i.e. 1 lightyear in about 1,400 years, and 1 AU in 8 days. The sun’s motion in the Milky Way is also more complex than might be immediately supposed[1]
    The orbital speed of stars in the Milky Way does not depend much on the distance to the center: it is always between 200 and 250 km/s for the Sun’s neighbours [2]. Hence the orbital period is approximately proportional to the distance from the star to the Galaxy’s center (without the power 1.5 which applies in the case of a central mass). The disk has a bulge at the center.
    The solar antapex, the direction opposite of the solar apex, is located near the star Zeta Canis Minoris.

    Source: The Encyclopedia of Astrobiology Astronomy and Spaceflight.

    The point on the celestial sphere, in the constellation Hercules, toward which the Sun is moving with respect to the local standard of rest at a rate of about 19.4 km/s (about 4.09 AU/year). The point directly opposite this is called the solar antapex and lies in the constellation Columba.

    Local Standard of Rest (LSR)
    Source: The Encyclopedia of Astrobiology Astronomy and Spaceflight

    A point in space that has a velocity equal to the average velocity of stars in the solar neighborhood, including the Sun. There are two forms of the local standard of rest.

    The dynamical LSR is a point in the vicinity of the Sun which is in a circular orbit around the Galactic center. The Sun’s motion with respect to the dynamical LSR is called the peculiar solar motion.

    The kinematical LSR, which is the form conventionally used by observational astronomers, is the mean standard of rest of specified star catalogues or stellar populations. The Sun’s motion with respect to an agreed kinematical LSR is known as the standard solar motion, defined as the average velocity of spectral types A through G as found in general catalogues of radial velocity, regardless of luminosity class. This motion is 19.5 km/s toward 18 hrs right ascension and 30° declination for epoch 1900.0 (galactic coordinates l=56°, b=23°). Basic solar motion is the most probable velocity of stars in the solar neighborhood, so it is weighted more heavily by the radial velocities of stars of the most common spectral types (A, gK, dM) in the solar vicinity. In this system, the Sun moves at 15.4 km/s toward l=51°, b=23°.

    Next, I need to decide whether the visual or the radio solar apex is best to use – my inclination is to go with the radio frame as it is specified more precisely.

    And of course to find the time to knock up a quick number cruncher to perform the rotation into the solar apex frame on the ephemeris!

  7. Some working through to get Solar Apex frame in ecliptic coordinates J2000.0:

    Obliquity of Ecliptic (2000.0):
    http://en.wikipedia.org/wiki/Axial_tilt
    23° 26’ 21.448�

    Coordinate transformation equatorial to ecliptic – adapted from:
    http://star-www.st-and.ac.uk/~fv/webnotes/answer9b.htm

    RA 18h 03m 50.2s = 270.9592 degrees = 4.72913 radians
    dec 30° 0’ 16.8″ = 30.004667 degrees = 0.5236802 radians
    obliq = 23° 26′ 21.448″ = 23.43929111 degrees = 0.409092804 radians

    sin(lat) = sin(dec) cos(obliq) – cos(dec) sin(obliq) sin(RA)
    lat = asin(sin(0.5236802) cos(0.409092804) – cos(0.5236802) sin(0.409092804) sin(4.72913))
    lat = 0.932692 radians = 53.439315 degrees

    cos(lon) cos(lat) = cos(RA) cos(dec)
    lon = acos((cos(4.72913) cos(0.5236802)) / cos (0.932692)) + pi
    lon = 4.68805 radians = 268.6055 degrees

    Solar Apex Frame Ecliptic Coordinates:
    longitude = 4.68805 radians = 268.6055 degrees
    latitude = 0.932692 radians = 53.439315 degrees
    ascending node = 6.258847 radians = 358.6055 degrees
    inclination = 0.6381043 radians = 36.560685 degrees

  8. Hmmm … my calculation above is obviously wrong, as 18h 03m cannot be 268.6055 degrees!

    Anyone wonder why I am unwilling to do much when pollen allergies are hitting me hard?

    Any, I found the NED online coordinate calculator and have used that instead:

    __________________________

    Solar Apex – Radio Frame:

    RA 18h 03m 50.2s = 270.9592 degrees = 4.72913 radians
    dec 30° 0′ 16.8″ = 30.004667 degrees = 0.5236802 radians
    obliq = 23° 26′ 21.448″ = 23.43929111 degrees = 0.409092804 radians

    NED Coordinate & Extinction Calculator Results
    Input: Equatorial J2000.0

    RA or Longitude = 270.95916667 = 18h03m50.20000s
    DEC or Latitude = 30.00466667 = +30d00m16.8000s

    Output: Ecliptic J2000.0

    LonEclip = 271.39449941
    LatEclip = 53.43931486

  9. Len, as you noticed the spammers seem to be relentless now, and the BadBehaviour spam blocker has been on the whole time but now seems to be missing a lot, so I’ve just raised the spam checking level to strict.

    I hope is does not interfere too much with people trying to make comments – if anyone’s comments get eaten by it, email me at:

  10. Love the site. FWIW, some folks have advocated calling the next solar minimum the “Al Gore Minimum”. I’d like to suggest that in addition to reminding them of the proper name “Landscheidt Minimum” that they be consoled with the suggestion to call the cold climate associate with it:

    “The Al Gore Cold Period” just a thought 😉

    I also suspect that it ought to be considered to be “Bond Event 0” since it fits the pattern…
