    Yes the webinar was very good, Lars. I’m pretty impressed with Peranso 3. I’m looking forward to the forthcoming updates with the extra functionality that Tonny was demonstratino.

    Not sure if it was recorded. I see a couple of folks have asked Tonny, but not seen his reply yet

    Yes you can download all the data from both databases. There is a link to the VSS db under “observations” at the top right of this page.

    There is an updated light curve on the VSS website: https://britastro.org/vss/

    Your dara show just how active this nova is!

    Graeme,

    you are welcome to write a note or article containing ToM’s for the VSS Circular. Or you can send ToM measurements directly to Des Loughney and he will include in the Eclipsing Binary News section. The VSSC is sent to Krakow.

    Good fun, James. I enjoyed that.

    Hello Tony,

    I am not an EB observer so I haven’t used that database. You could drop a line to Des Loughney, VSS EB officer (contact details in the VSS Circular) to see if he knows.

    I’ve just imaged IX Dra from my home obsy: mag 17.4C at 17.24 UT

    Was this also with your 80mm frac, Graeme? Really shows what’s possible with a small scope plus CCD.

    I wouldn’t worry too much Darren. For photometry try what you have at hand first before shelling out on more stuff. If you want to go to the nth degree in photometry you can try something else later. If it helps, I generally run my CCD camera 2 x 2 binned for photometry. There is nothing inherently wrong with binning.

    Thanks Graeme. That is helpful. Try on other evenings if you can.

    I just updated the LC with data up to 2021 Jan 2. The last data points hint that might be beginning to fade a bit faster. Keep watching!

    When making this plot, I was struck by the undulations in the LC at ~daily intervals. I’ve not looked into whether these are artefacts or genuine.

    A quick reminder that we are only a few days away from the next superoutburst of IX Dra (perhaps 3 to 7 days). Hence observations are encouraged.

    I had it at mag 17.1 last night (NY Eve) – just declined from the last “normal” outburst”. The next outburst could well be the super…keep watching!

    Nice work Hugh.

    There is also a paper by Mark Kidger on Betelgeuse in the December Journal.

    The original Betelgeuse Forum thread you mentioned is here.

    Here’s a light curve of the Nova which Philip Jennings just showed at the BAA meeting.

    Prepared yesterday (Dec 4). Latest obs early this AM put it at mag 8.9

    Still bright – last evening I had the nova at V~8.3. Technically this is an easy binocular target, especially now the Moon is receding.

    This nova is still bright. I had it about mag 8.5 last night.

    The nova now has an official variable star designation: V1112 Persei

    yes indeed. I had it at mag 8.9 at 18.30 this evening.

    You need a smaller telescope, Nick! I was using 5 sec exposures on the C11.

    Good target for visual observers even with relatively small instruments.

    Super to have another northerly nova.
