New England observer Lew Gramer, fresh back from his mid-November fish observing and meteor-catching expedition in South Florida, reports that December also promises to be a great month for celestial sky-sparks!" ... Other showers adding to the mix this month include several very minor showers, such as the Chi Orionids (3 Dec), Monocerotids (9 Dec) and Sigma Hydrids (12 Dec), which usually contribute no more than 2 or 3 meteors per hour during even post-midnight observing this month. ...

On September 15, 1998, the STScI director, Dr. Steven Beckwith, announced a special observation opportunity to the astronomical community during the Leonid Meteor Shower. During the peak of the Leonid meteor shower on November 17, 1998, HST will be pointed near the anti-radiant for ten hours. Anyone who is interested can submit ideas to STScI for scientific observations during this time. ... There are no HST observations in the archives for objects in this field. ...
