On the evening of Dec. 3/4, 1999, Saturn occulted the star PPM 118428.
[m(v)=9.20 sp.=G0 02:40:16 +12 53 53] Immersion occurred at 06:43 UT for
our site at the Kuiper Observatory on Mt. Bigelow just north of Tucson
(-110 43.9 +32 25.0 alt.2510m). We used the PCCD occultation camera system
to observe the event with a Methane interference filter. Many large
"flashes" were seen as the star's light passed through the Saturnian
atmosphere. They can be seen in this speeded-up movie of immersion
below.
