We have witnessed another intense eruption, this one today (November 21.45 ¡À 0.12), which was first detected thanks to a?COMET CHASERS?image scheduled by Maria Eleftheriou. Pepe Manteca had taken an image from Chile using the iTelescope T72 instrument that showed the object entirely quiescent about 8 hours earlier. We have obtained multifilter images within about 6 hours of the eruption (intensity = 79 nucleus-equivalents). ? A lot more information is available on the and the . ? This event came about a day after Errol Simpson of COMET CHASERS obtained deep 2.0-m images of the pseudonucleus showing the previous mini-outburst coma. Images reproduced below - Note the asymmetric outburst coma close to the nucleus directed towards roughly p.a. 45¡ã ? ? Here's what 29P looked like a few hours ago (image 6.2 arcmin across) after its latest intense eruption - essentially stellar in appearance, magnitude 13.2R 0029P ? ? ? ? C2024 11 21.72727 10 10 29.52 +09 34 10.8 ? ? ? ? ?13.19R ? ? ?Q62 ? What will this new intense outburst coma look like in a few days? Richard Miles BAA |

A few weeks after your reported outburst, 29P on the morning of 2024 December 5 0947UT was magnitude G=11.4 as calculated from 60x10 second images taken thru a green filter in an aperture diameter of 2.4', which includes the coma-tail complex. If one looks at the brighter part of the coma, aperture diameter of 1', the magnitude is G=12.3. |
