 Cuno Hoffmeister - Wikipedia, the free encyclopedia
Cuno Hoffmeister (February 2, 1892 - January 2, 1968) was a German astronomer.
Cuno Hoffmeister founded the Sonneberg Observatory and discovered approximately 10.000 variable stars and several asteroids.
Hoffmeister crater on the Moon is named after him, as are the asteroids 1726 Hoffmeister and 4183 Cuno.

 Cuno Hoffmeister (1892 - 1968)
The biography of Cuno Hoffmeister, one of the most distinguished specialists for variable stars in the history together with an attempt to estimate critically his contribution to various branches of astronomy.
Hoffmeister a jeho spolupracovníci přitom sbírku doplňovali i za podmínek vysloveně nepříznivých, a to nejen z hlediska meteorologického.
Hoffmeister zmíněnou teorii skutečně rozvíjel v několika pracech, zejména v knize Meteory [3], která byla později často citována.

As early as 1943 Cuno Hoffmeister suggested that the direction of the Type I tail was determined by corpuscular radiation from the Sun.

The Alpha Aurigids were discovered by Cuno Hoffmeister and A. Teichgraeber (Sonneberg, Germany) on the night of August 31/September 1, 1935 (Solar Longitude=158 deg).
Hoffmeister examined his own annual observations made near the end of August and in early September, and noted probable detections of this shower in 1911, 1929, and 1930.
Hoffmeister concluded that, although activity seems to have been present since the comet's perihelion passage, there is no evidence that the Alpha Aurigids are a permanent shower.

The discovery of this stream seems attributable to Cuno Hoffmeister and is a major segment of his vast "Scorpius-Sagittarius-System" discussed in his book Meteorströme (1948).
Hoffmeister noted that numerous active areas appeared in this region of the sky beginning in late April and ending in mid-July.
Hoffmeister referred to this radiant as representing the "distinct core" of the Scorpius-Sagittarius system and he described the activity as a "flat maximum at 75 deg to 80 deg."

Cuno Hoffmeister was the first to officially recognize the Piscid stream.
Although Hoffmeister gave no exact details about his possible northern and southern Piscid showers, a table was given which demonstrated the general motion of the radiant.
But while this stream possessed similar characteristics to Hoffmeister's Piscid stream, the orbit revealed several strong dissimilarities, notably a 20 deg difference in the argument of perihelion, a 21 deg difference in the ascending node, and a 0.12 AU difference in the perihelion distance.

 Cuno Hoffmeister - Wikipedia
Cuno Hoffmeister folgte mit dem Konzept der "Sonneberger Himmelsüberwachung" einer Anregung Paul Guthnicks, der Anfang der 1920er Jahre an der Universitätssternwarte Berlin-Babelsberg die Einrichtung einer systematischen fotografischen Himmelsüberwachung zur Diskussion brachte.
1930 und 1933 unternahm Cuno Hoffmeister zwei längere Forschungsreisen in das Karibische Meer.
Zwischen 1937 und 1960 hielt sich Cuno Hoffmeister zur Erforschung des südlichen Himmels mehrmals längere Zeit in Südafrika und Namibia auf, wo heute das "Cuno Hoffmeister Memorial Observatory" in Windhoek an ihn erinnert.

 Re: (meteorobs) A-T 1996 ZAYGE ...long article
The current record holder (albeit posthumously) is Cuno Hoffmeister, whose plots over a period of about 30 years revealed several thousand radiants.
He detected the A-T's in six different years, including 1934, when it was also seen the same night by an observer in the United States.
Hoffmeister's radiants were all listed in his 1948 book Meteorstrome.

 C&MS: The Corvids   (Site not responding. Last check: 2007-11-04)
The Corvids were discovered by Cuno Hoffmeister during a meteor expedition to Southwest Africa in 1937-1938.
The radiant was determined as RA=191.6 deg, DECL=-19.2 deg on June 28, although it was described as diffuse, with a diameter of nearly 15 deg.
Hoffmeister computed two orbits based on semimajor axes of 2.5 and 3.0 AU and noted "a rather striking resemblance to the orbit of Comet Tempel 3-Swift, except for argument of perihelion...." Interestingly, today's knowledge of asteroids has produced another possibility which seems more attractive than Hoffmeister's---Apollo asteroid 1979VA.

The object was discovered in 1958 by Cuno Hoffmeister at Sonneberg [1], together with V396 Her.
Hoffmeister found brightness variations between 15.7 and 16.7, stating, that the object shows long stillstands between brief periods of of activity.

 The Solar Wind
While the dust tail was much brighter, the plasma tail had a different color, tending towards the blue.
Sunlight pressure cannot explain such behavior, but in 1943 Cuno Hoffmeister in Germany, and later Ludwig Biermann, proposed that apart from sunlight, the Sun also emitted a steady stream of particles, a "solar corpuscular radiation" which pushed the ions.
Variations in the speed of the particles would explain the accelerations, and the tail did not point straight away from the Sun because the flow velocity of the particles was not too many times larger than the velocity of the comet itself.

Chapman was mostly interested in auroral data from middle and low and since the IGY this part growth up(Chapman, Paton, Hoffmeister, Schršder and others).
Therefore the work by Paton and the German Cuno Hoffmeister are studied well, including the development by the research of Fogle, Chvostikov, Schršder, Saronov,Vasilyev, Villman and Witt.
Also the development of the idea of the solar wind from the data by Hoffmeister from comet tail measurements and later conclusions by Ludwig Biermann are studied and will be published in the journal of the commission.

Penston noticed in 1968, that the object is identical with the variable star BW Tau in the constellation Taurus, discovered in 1940 by Hanley and Shapley at Harvard College Observatory.
The second case was BL Lac, a variable star in the constellation Lacerta, found by Cuno Hoffmeister in 1929 at Sonneberg.
Most of the variables were discovered at Sonneberg by Ludwig Meinunger (6), Cuno Hoffmeister (5) and Herta Gessner (1); see Hoffmeister’s classical book [2].

 (meteorobs) A-T campaign 96: Part 2
First, Hoffmeister and the AMS observers of 1934, 1940, and 1951 were all very prolific observers, with the AMS observers being among the most prolific and experienced observers in that organization's history.
Second, although Kronk was unable to uncover the criteria for Hoffmeister's list, he did note that during the days of Charles Olivier the AMS criteria for radiant determination was the intersection of four or more meteors within a circle of no more than 2.5 degrees, which is more stringent than what some groups accept today.
Taking all known visual observations of this radiant into consideration,it should be noted that not only was this radiant independently found by two experienced observers in 1993, but it was also independently found by two experienced observers in 1934, 1940, and 1951.

Their explanation led to many ideas about material ejected from the solar surface and launched into interplanetary space.
The real turning point for investigating the 'solar wind' came in 1943 when German astronomer Cuno Hoffmeister showed that comet tails were actually deflected by this wind.
Careful studies of cometary gas and dust tails showed that the gas tail deviated by many degrees from the direction they should take if only the pressure from sunlight was involved.

 The names and catalogues of variable stars
Thus, initials HV, in use as early as the end of the XIXth century, mean "Harvard Variables" and designate the stars discovered at the Harvard Observatory (more than 10000!).
Initial S is attributed to the variable stars discovered at the Sonnneberg Observatory in Thuringia (Germany) - also over 10000, mostly discovered by the famous variable star observer Cuno Hoffmeister who started his career as an amateur.
Letters HBV are used by the Hamburg-Bergedorf Observatory, VV by the Vatican Observatory, TV by the Tokyo Observatory, BV by the Bamberg Observatory whereas all the variable stars discovered by the Russian observatories have the provisional designation SVS meaning Soviet Variable Star, the English translation for Sovietskii Peremenesti Zvezd (SPZ).

The Southern Chi Orionids were not well observed during the first half of the 20th century, but numerous observations were made of the northern branch.
Most notable was the inclusion of the Northern Chi Orionid radiant in a table of "third grade radiants" in Cuno Hoffmeister's 1948 book Meteorstrome.
Ten radiants were isolated which were active around December 11 (solar longitude=259 deg) from an average radiant of RA=83 deg, DEC=+22 deg.
