This page is about imaging for science.

Not just taking pretty pictures – but gathering data for various science projects such as:

  • HOYS – Hunting Outbrusting Young Stars
  • ExoClock – exoplanet transit timing associated with the ARIEL mission
  • BAA – variable star section
  • AAVSO – American Association of Variable Star Observers
  • GOSA – Asteroids light curves and GAIA
  • COBS – Comet Observation Database
  • GMN – Global Meteor Network
  • UKMON – UK Meteor Network

Markarian 421 – which is actually a Blazar, at an easier than most mag. of 13.4, right next to a really faint galaxy (LEDA 33453) at mag 19.6. This one is only 411 million light years away.

The comet “meant” to put on a naked eye show in 2024. Still very far away and faint at about magnitude 17. Stacked on the comet so the stars trail and the comet remains still. Very faint at a mag of about 17 and come size 0.5′

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.

C/2022 E3 (ZTF) in R

27 January 2023|Comet, News|

Brighter still. 3 tails including sunward pointing one. Ion tail is twisting having suffered a “discontinuation event” caused by CMEs from the Sun.
