PULSE@Parkes session at
science fair allowed us to obtain a large number of pulsar observations.
To the delight of the students and their teachers, many of the pulsars were
observed as they underwent interesting events. For instance, we managed to
catch PSR J1107-5907 switch from a weak emission state into a strong state
(see the central panel in the picture to see that the pulsar switched into
the bright state about 7 minutes after the start of the observation; the
top panel shows the pulse profile averaged across the entire observation)
and then later it seemed to switch completely off. This is the same pulsar
that was recently
observed to switch into its bright emission state using
the Australian Square Kilometre Array Pathfinder telescope (ASKAP).
