B0833-45 Daily Observations

Daily observations are initiated by a scheduling robot, a function of the Virtual Control Panel (VCP - a custom C# Windows application), followed by automatic analysis and website upload.

The primary aim of the daily observations is to measure the spin frequency of the Vela pulsar and attempt to detect a 'glitch', a sudden increase in spin frequency (usually in the 1-2 ppm range) which interrupts the normal slow decrease in spin frequency. The time between Vela glitches averages 2-3 years.

The automated daily observations commenced May, 2017 and at the time writing, have completed over 2 years of daily observations (98.5 % up-time).

Below are the last HawkRAO observatory results of reception of Vela pulsar signals showing the Observatory Status, the Period Search Panel, the Glitch Monitor Panel, a Vela Information Panel and an Aggregate Pulse Profile.

For further details about the data displayed here see the 'Information' page.

Also available is a daily observation summary text file and details of science results on the 'Science' page.

The current position of the Vela pulsar as observed at HawkRAO can be viewed on the 'Vela' page (see tab above).


On the 1st February 2019 at 14:09 (UTC) Vela 'glitched' (refer to ATel #12466).

The glitch (~ 2.5 ppm jump) was clearly seen in HawkRAO data in the MJD 58516 observation as
shown by the jump in the spin frequency trace (light blue line) in the 'Glitch Monitor Panel' below.

This is the first time that a glitch has been recorded and notified
by an amateur radio astronomy observatory - in any pulsar.
