[BAA Comets] C/2015 ER61 (and not C/2015 V2!!!!!) - increase in magnitude

[Tony Angel]

I hope that I have the correct name now LOL.

Just received a message from Rolando confirming outburst. Others have also increase in coma size including Neil Norman. 😊

Images to be posted shortly. Will observe in the morning – subject to weather. I will then not be able to observe it for a week. ☹

Best wishes,

Tony.

Sorry all.  I had been awake most of the night .  Brain was a little fuddled. Although I had observed C2015 V2 in the middle of the night, it was C2015 ER61 – my last observation of the session – that I was referring too.
Dennin. Yes I will send images shortly after a cat nap. I had hoped to have gone to bed after I shut up this morning, but by the time I had finished answering various queries it was time to be dragged away to the shops, from which I have just got back.

Meanwhile Jakub Cerny worked on two days stacked images that I had sent to him and he has returned his results based on my images:

“I select R magnitudes because in R your ccd chip is most sensitive, it shows 10.0 mag yesterday total magnitude and 8.4 mag today”

Meanwhile Part II.

Before I went out, after mentioning to Rolando Ligustri about the increase he told me that NM was cloudy. When I got back there was a message from him that NM was now clear. Hopefully he will be imaging it.

Best Wishes,

Tony.

Ooops. I've just noticed that your subject says 2015 V2 but your
observations are of 2015 ER61.

Ignore my previous email...

Nick.
