By all indications, this new meteor shower will produce some bright meteors and the Zenith Hourly Rate (ZHR) could be between 100 and 400 meteors per hour. As far as is known, Comet Linear presently does not produce that much dust and is transitioning from an active to an inactive comet. It has been shedding dust since the 1790′s until the present. It is estimated that the size of the particles it sheds are about 1 mm in size.

Sky and Telescope magazine has this to say about the prospects:

“As Ye and Wiegert report [see first link below] in an upcoming Monthly Notices of the Royal Astronomical Society, the team’s calculations suggest that the comet has been producing relatively large particles (on the order of 1 mm), meaning that the upcoming meteor shower may be chock-full of bright meteors. But their work also places limits on the overall rate of meteors, suggesting a rate of 200 per hour under ideal conditions.

“That’s in the same ballpark as previous, independent work by Jérémie Vaubaillon (IMCEE, France) and Mikhail Maslov: Maslov, for example, estimated between 100 and 400 meteors per hour. But Ye and Wiegert warn that, “given the current relatively weak dust production of the comet, rates could be much lower.” With the low dust production, as well as the team’s lower estimate of how many debris streams from the comet’s previous passes are hanging around in this region of space, it’s highly unlikely that we’re in for a “meteor storm” (1,000 per hour) — although the team couldn’t quite rule it out.”

Comets leave behind dust and small particles in their trails. Boulder-size and larger sized objects only result if the comet breaks apart. By all indications, this hasn’t happened for this comet. Anyone predicting doom and gloom from some sort of large meteor bombardment are grossly exaggerating the facts of the matter. 1 mm sized particles will produce a nice light show, but are hardly cause for concern of damage.
