Following the detection of early
superhumps in ASAS 023322-1047.0, the object
entered its main outburst stage on 2006, Jan 28th,
trading in early superhumps for regular superhumps.
Hiroyuki Maehara (Japan) announced that his Jan 28th
CCD observations (JD +763.9) show full superhumps
with an amplitude of 0.2 mag. Our own observations
of Jan 27th (JD +763.4) only revealed early
superhumps with 0.05 mag amplitude. The transition
must have been fast and quite spectacular.
Main outburst stage - regular superhumps
So far, we have collected 4 observation sets,
with a total of 952 observations, covering this
stage. Using the ANOVA
method, we find a superhump period Psh = 0.05579
+/- 0.00027 d, and a superhump amplitude of 0.3
mag. The superhump period excess value of ASAS
023322 thus becomes 1.7%.
