Re: Leonid cloud observed in 1998 (Re (meteorobs): Perseid & Leonid clouds)
Not if they are observing in the general direction of the anti-radiant.
Another point is that the cloud intensity is greatest when the trails pass
INSIDE the Earth's orbit (with no substantial Leonid activity) and the
line of sight is a tangent to the dust trail orbit some distance from the
Earth.
Remember that the HST observed in towards the Leonid anti-radiant in 1998
to minimise impact damage to the mirror, but still remain functional.
But, yes, observing towards the radiant during a storm would seem
inappropriate!
Thought. If a space telescope observed the apparent anti-radiant when the
Earth passes thru it, the scope would see point meteors going AWAY from
the telescope!
