About - Classification Values after Malde
Observing the
increasing sunspotactivity in Solar Cycle 21, I always had
thoughts on how to determine a better observing value for the
amateur. This was mainly due to my new interest in
plotting the Solar Flux, at that time observed from Ottawa in
Canada. I felt that the solar flux appeared like measuring
the temper of the raging sun, sometimes in quite a good mood,
while at other times mad with anger.
It was then that I cast my eyes on the 7 Zürich-letter codes
that now have been used for more than 100 years. Dr.
Patrick S. McIntosh revised them to his 60 letter
Zürich/McIntosh-classification system, published in 1973, and
are daily used by the observatories worldwide.
In July 1978 I started puzzling with the letters, finding that I
had to study the behaviour of all the apparent 60 classes.
They were investigated for their ability of survival on the solar
disk, their structure and complexity and also study the typical
lifestyles from hundreds of sunspotgroups. This took me
just about 3 years to complete satisfactory.
Then I had, for three years puzzled with attaching numbers to
these three-letter codes, so that one can do calculations with
them. In late 1997 I even made CV-numbers out of the
official USAF-observations from 1971 to 1997. Monitoring of
these observations and compared to CV-Helios Network's own
observations are performed on a daily basis. The results you may
see somewhere else at these pages.
On the 15th of August 1981 I declared the system
"Classification Values" for "official".
The system was tried out and published in the norwegian
"Amatĝrastronomen", and the first two other norwegian
members joined in the same year, 1981.
In the summer of 1982, I had contact with Dr. Rainer Beck in
Bonn, Germany who was greatly involved with the "vereinigung
der Sternfreunde, fachgruppe Sonne", in Germany.
I wrote an article in english sometime later and he kindly
introduced the system there in late 1985. The first
german and swiss observers came in 1986. Since then the
members observing the CV has grown from a few observers hence
performing a modest number of observations a year, and up to
today, when we are now about 40 observers and we perform about
6000 observations per year!
I like to thank every CV-observer, any CV-member or any who find
interest in reading this, and for believing in the Ultimate Way
of Observing the Sun, the Classification Values!
Oh,
Helios, The Sun of ours; Our Lifepreserving Source of Light!
May you shine upon all of us, not only at Day, but also at Night,
telling all creatures, every living spirit, every man on Earth,
to hold peace with each other, this thought God gave birth!
