Astropeiler Stockert - Wolfgang Herrmann

NOTE: The PDF describing Pulsar activities is presented here with permission. Further information about the Astropeiler Stockert facility can be found at the end of this page.

The group at Astropeiler Stockert has succeeded at detecting over 75 pulsars as detailed in this PDF (5 MB).

NOTE: this number has increased over time and was 88 as of the 31st December, 2015, (including two binary pulsars) making this the most successful amateur observatory in terms of the number of pulsars detected.

Of particular interest in that PDF file is the profile of B1919+21 - the first pulsar discovered by Jocelyn Bell in 1967.

One can only dream....

Other Details

I asked Wolfgang a number of questions about the width and depth of the pulsars detected and he kindly provided the answers as below...

How many pulsars in total is that now ? 88 up to now

What is the weakest pulsar you have detected ? B2044+1515, 1.7 mJansky @ 1400 MHz

Wolfgang qualifies the term "weakest": The "weakest" pulsar in terms of average flux may not necessarily be the one with the weakest signal. Signal to noise also depends on the duty cycle (sharp narrow pulses give better SNR than wide pulses). Also the state of the scintillation will influence the measurement result.

What are the fastest and slowest 'spinners' you have detected ?  Fastest: B1937+21, 1.5 msec ; Slowest: B0525+21, 3.7 sec

Wolfgang added these comments: You may also be interested in - Lowest dispersion: B0950+08, DM=2.96 ; Highest dispersion B1815-14, DM=622

Wolfgang notes: Two binary pulsars have been detected.
