Now is:

Mon Aug 2 11:20:07 CEST 2021

Guestbook

My guestbook is on-line again. This time (somewhat) protected against spamming.

Notes

about setting up different things with computers.

Bug report

A well written report about bug that I found. I always find that bugs are fixed much faster if I not only say that something is not working, but also why it is not working.

Hobby

I participate in The Great Internet Mersenne Prime Search. This is a distributed computing effort testing Mersenne numbers to see whether they are prime or not.

There is a web forum, www.mersenneforum.org where I sometimes participate under the forum name "patrik".

My best posts

Number of zeros in the (at the time of the post) largest known Mersenne prime
Digit missing in pi ASCII graphics

Nördiga postningar (title yet to be translated into English)

Importance of CR or CR/LF for GMP-ECM
Assembly programs for calling CPUID

Gravity measurement

Gravity measurement in Haparanda archipelago

My colleague Niklas Juhojuntti is making a gravity measurement on Ormskäret in Haparanda archipelago in August 2013.

Avvägning av grundvattenrör

The equipment used for measuring height when measuring gravity can also be used for other purposes at the Geological Survey. Here the groundwater level above the geoid ("sea level") is measured. This is a different but similar equipment than in the video clips above, which does not have the receiver built into the antenna.

Daily max and min of magnetic declination /kompassens missvisning/ at Uppsala Geophysical Observatory

The first plot shows the daily maximum and minimum value of the magnetic declination at Uppsala Geophysical Observatory, about 20 km west of central Uppsala. The median, and 10th and 90th percentile are also shown. E.g. on February 04, we see that the declination momentarily exceeds 5.7 degrees.
The second plot shows daily mean values (the blue curve), quiet days and monthly means (of quiet days). The quiet days are the five international quietest days, derived from the Kp index and published by GFZ Potsdam. The average of the field for these five days is then representing the monthly mean (the green line). When most of the quiet days occur in one end of the month, this approximation is less good (e.g. October 2010: 1, 2, 3, 4, 14).
(I describe how the plots are created here.)

These K indices have been computed at SGU using the FMI algorithm developed at the Finnish Meteorological Institute.

Planetary K index Kp

The Lovö observatory is one of the 13 observatories used to derive a global K index, the planetary Kp index. Read more about this at GFZ Potsdam. Here you can view the so called Musical diagrams of the Kp index (explained under "What is the Kp index?").

Geomagnetic C9 Index (Daily Character)

Each day gets an index from 0 (quiet) to 9 (very disturbed), plotted in different colours. This plot has a width of 27 days (+6 overlapping days) to enhance repeated disturbances due to solar rotation.
2009 was particularly quiet.
