Previous message: [isoncoma] Comet ISON Coma Morphology Campaign --- Alert

Dear Colleagues,

Emmanuel Jehin and colleagues (in visible) and Jacques Crovisier and colleagues (in radio) report that comet ISON is in outburst.

Best regards,

Nalin (on behalf of Beatrice Mueller, Matthew Knight, Tony Farnham, and himself)."

And more:

"Very good news, TRAPPIST ISON production rates (all gas species) have been x2 in only 24 hours !

We now reach about 2E28 mol/s for Q(OH) at 10.000 km. It looks like an outburst is going on, as the increase was not as fast the last 4 nights, We now see also jets in OH bands same location as those of CN and C2. AfRho from dust continuum is only rising a bit, R and V broad band flux have also increased by factor 2,

We should be able to get images until Nov. 18, but window is only 20 minutes now and comet below 15 deg,

Clear skies,

Emmanuel Jehin"

"Our recent observations also show an acceleration of the increase in brightness : 1 mag. /24 H"
