Dear all,
Since our last report and major outburst on Nov. 14, the ISON production rates
were dropping. We lost about a factor 2 in all measured quantities in 4 days.
No sign of breakup in the images.The dust features in our pictures seem to be
linked to the active regions identified earlier in C2 and CN.
But this morning 19.37 Nov UT, we found ISON very active again !
All the production rates have been x ~6 since last night, while the AfRho,
maesuring the quantity of dust, was only x ~2.
This looks to us to be the start of a new outburst linked to the active regions,
as the jets are today strong again.
Our campain is unfortunately nearly over with TRAPPIST, but we will try to point
it again the next couple of nights and confirm this new rise.
Is there new visual estimates ?
=> 真的嗎?
那表示 ISON 接下來會噴更大
