   Oops, these outbursts fell between the gap of pre-VSNET and
VSNET era.  Extracted observations from IAUCs at the time:

(IAUC 5778)
AQRVY 19930424.59 <135 WAl
AQRVY 19930424.70 <130 Jon
AQRVY 19930425.57 100 WAl
AQRVY 19930428.73 103 Jon
AQRVY 19930429.68 103 Jon

(IAUC 5979)
AQRVY 19940422.72 <130 Jon
AQRVY 19940423.715 113 Jon
AQRVY 19940423.751 115 Jon

   We can't yet explain the difference between historical records
(8 and 9 mag) of outbursts and recent ones.  The object may have
behaved differently (WZ Sge-like at times?) at different epochs.
