SCB comments : “ both of them could be caused by air turbulence or by some failure on my eye”. That is probable since the second occultation would require a 150km body, whereas (342) is estimated ~65km only.

Special Event:
Following a warning from Bruno Sicardy (Observatory of Paris-Meudon), EAON called to observe Tethys - one of the large Saturn satellites - occulting a Mv 9 star, as it has been done for Titania on 2001. Unfortunately, north-western Europe has been covered by clouds.
2002.12.15 : TETHYS / TYC 1310-02435-1 CAS CNS COF FRP GCV
GRM IZF PAH SCB
We received two positive
reports from Europe (BZY and NVI) and seven positive reports from the
Japanese Occultation Information Network. BZY
recorded the event with a camcorder and observed visually a TV screen. The
visual timing of reappearance was poor, and was eventually deduced from duration
39.95s ± 0.1s , obtained by Janusz Wiland from monitoring the magnetic tape.
