(165) Loreley occults UCAC4 617-008946, Oct 22nd-evening.

This is an IOTA event with a target magnitude of 11.7, magnitude drop 1.1 and maximum duration of 15 seconds at a helpful pre-midnight time ( 2339-2342 BST ) and at a good altitude in Perseus.  So a lot in its favour with the prospect of positive chords over a wide area of England, Wales and northern Europe.  Observations are invited, weather permitting of course.   Moonlight might interfere a bit, but no too much i hope.

It would be worth while to observe this prediction from all parts of the UK,  to detect any secondary events that might be caused by a satellite, although none are currently known.

Its a potential visual target and certainly for video or CMOS cameras, or a star trail in a fixed instrument.  The prepoint method can be used to find the star.  Center the telescope on 7 Trianguli and wait 46 minutes.  The target should then be close to the field center. ( RA target, 03h 02' ;  RA 7-Tri, 02h 16' - epoch of date).

Best of luck ! - Tim.

Friday night occultation

Thanks Tim for alerting via the Observers' Forum.

Here in Dorset the sky may be cloudy, I fear.

Good luck tonight

Richard/All,  Good luck to everyone tonight. The weather forcaste over Oxfordshire has been variable,  A day ago it was 100%cloud. Now only 15%.   So i live in hope that I get a chance, and Moon light does not interfere.

No luck here

My thanks to the nine observers who indicated they would be attempting this, but were clouded out !   I had set up a second telescope  (8" F/4) in the garden to make a duplicate observation by video.  This could be compared with the CMOS camera.

What i found were a few technical problems with the video setup, which I was able to correct. So this was helpful at least.
