Intranight optical variability of radio-loud broad absorption line
  quasars
  We present the results of an optical photometric monitoring program of 10
extremely radio loud broad absorption line quasars (RL-BALQSOs) with
radio-loudness parameter, R, greater than 100 and magnitude g_i < 19. Over an
observing run of about 3.5-6.5 hour we found a clear detection of variability
for one of our 10 radio-loud BALQSOs with the INOV duty cycle of 5.1 per cent,
while on including the probable variable cases, a higher duty cycle of 35.1 per
cent is found; which are very similar to the duty cycle of radio quiet broad
absorption line quasars (RQ-BALQSOs). This low duty cycle of clear variability
per cent in radio-loud sub-class of BALQSOs can be understood under the premise
where BALs outflow may arise from large variety of viewing angles from the jet
axis or perhaps being closer to the disc plane.
