(meteorobs) South Delta Aquarids
Hello
I'd like to confirm Pierre's comment on the activity of the South
Delta Aquarids... well with a radio system it is hard to tell but the
activity is very strong and starts not long after the radiant rises.
You can see from the data below the steady strong rise 13 -> 14 UTC
(11 pm -> 12 midnight local). I'm also surprised at the sudden
decrease after the peak. I'm not sure if it's geometry or a sharp
trailing edge to the stream.
Last night's peak of 140 is quite high for my system. I'm keen to see
how it goes tonight (now 8pm). I might even rug up and have a look
outside ;-) The normal early morning peak time is also now building
up.
thanks
Bruce
