29P Outburst discovery 2024-03-24

25 March 2024|ASERO, Comet, News|

Discovered using the ASERO/Murrell. I was taking 5x60s stacks and using Astrometrica to measure and quickly noticed that 29P was getting much easier to see with a better SNR. Had originally planned to take several such sets separated by 1 hour but events overtook this plan.

—– end —–

So I put a post on the BAA comet group asking for help confirming and emailed Richard Miles to alert him. He asked that I start continuously imaging 29P and measure individual frames as we seemed to be the only ones with clear skies. Many more subs were taken to confirm the comet had increased in brightness from about 16.7R to about 13.7R, a significant outburst. Later on as as we lost the sky to clouds, telescopes in Chile and other parts of the world were able to take over.

Richard requested the first 5 FITS files to determine that the outburst started on the 3rd sub we took. I also sent the remaining subs and Astrometrica files and he produced a preliminary plot using a 3px radius aperture:

All the data are now on the BAA 29P project page.

Alert on the comet group:

ALERT: Strong outburst of 29P/S-W1 discovered by Mark Phillips of the Astro Soc. of Edinburgh (ASE), Scotland
Richard Miles Mar 24 #298
Mark Phillips has only recently joined the MISSION 29P initiative using the ASE’s 0.3-m remote telescope in Spain and has struck very lucky with this discovery of a 13th magnitude outburst of 29P/Schwassmann-Wachmann 1..

This is a particularly important discovery as I expect there to be one or two further strong outbursts during the next 5 days.

The reason is that this event comes 107 days after an earlier very strong outburst, which itself happened 114 days after a previous strong outburst in early August detected by Jean-Francois Soulier.

The time interval corresponds with almost exactly two rotations of the nucleus indicative of a highly-active region on a small fraction of the nucleus surface.

Importantly both these earlier events were followed by at least one further strong eruption within the next 5 days of the first.

We may also see a further step-change in brightness within the next 24 hours as happened in early December.

Well done, Mark!

Further monitoring is much encouraged.

Very bright fireball over Scotland 2023-02-05 UK007J

5 February 2023|Meteorcam, News|

Details here: https://archive.ukmeteornetwork.co.uk/reports/2023/orbits/202302/20230205/20230205_022512.269_UK/index.html

Data from UKMON

Mark McIntyre of UKMON says on the GMN forum:

Bright visual mag -5.9 fireball over Scotland last night. Abs mag at least -9. Asteroidal in origin, travelled about 50km over NE Scotland between Aviemore and Dufftown.

Unfortunately going too fast I think – entry velocity 24 km/s, slowed down to ~15km/s before disintegrating at ~35km, so not much chance of ground debris which anyway would probably have gone into the sea north of Elgin.

We are getting a lot more coverage of Scotland now, several cameras onboarded in the last few months and more to come.

Those are mostly ASE cameras that we’ve been adding. At an abs mag of almost -9, that’s brighter than the brightest from 2022, caught by my UK006E during the Perseids at -6.77.
