Asteroid Positive Elektra in 2010

Knowl Hill Observatory is a 3m dome in Plywood (10mm and 3mm ) build in 1991, opened March 21 1992. The manually operated dome moves on casters around a wooden track supported on a low breeze block wall. An up and over door allows the user to step in over the wall into the dome. A skin of 3mm exterior ply has fiber glassed joints and is painted. A good paint job lasts 2-3 years. Heavy snow in 2010-2012 caused significant damage and some areas of the exterior have now been reinforced with fiberglass. The door was covered (2013) with a layer of Flashband for additional weather proofing. Here is a recent photo   The OTA was flocked in 2015, and a 10:1 focuser added. Occultations is the main interest but as you see from my log page I like to image most objects. .

Joining the UK discussion group on occultations.
The Yahoo! group UKoccultations was set up in 2012 to bring local occultation observers into contact, and to share insight, result and news. The membership is not limited to UK observers.

Knowl Hill

Bright Green Bolide

A mag 8-10 (est) bolide lit up the ground at 0000hrs on the 24/25th at midnight. This was reported to the UKMON network and BAA. Richard Fleet recorded it with his 8 camera station at Wilcot (SW). I was outside observing occultation at the time. There was no noticable persistant train.

The bightest meteor I have seen since the great 1998 Leonid fireball display.

Imaged with an ATIK 428EX (2x2 bin) at -15C. Stacked with DSS (FITS output) and tweaked with AstoArt5. Instrument: 30cm F4 with Baader MPCC auto guided with SkyWatcher 80mm F5 and PHD2.

Triton Occults a v12.7 star OBSERVED

After much prior testing and planning, a x2 Barlow and W25 filter were used to image the event with WAT-910HX video camera. Integration time was 0.64s. The recording was to the HD (A2D dongle) using OccuRec software in AAV format. The fades were about 6-10s and the duraton about 142 sec. FITS files were sent to Paris Obs (Bruno Sicardy). I have a movie to summarise the event:

(31) Euphrosyne - Second asteroid positive this year

After a number of high-profile (bright stars) were clouded out recently, this prediction for a 0.3 mag drop was successfully recorded in good conditions. The smallest light drop in some time, is shows that the video limit is about 0.2 to 0.3 magnitude, providing the duration is long enough. This was 7.4 sec. and a 0.25 width path shift is suspected towards the NW. More on the asteroids page.

(3122) Florence fly by

Asteroid (3122) Florence - size 7km. passed the other side of the Moon in this NEO approach to Earth. Aracebo radio telescope discoverd two moons and one appeared to be a contact doublet. The image wa aboutan hour in lenth with images taken 1 min apart

Triton by integrating video

While planning for the Triton/stellar Occultation on Oct 5th 2343-2353 UT, I captured some video with WAT-910HX at 0.64s integrated frames. Triton is there at Mag 13.5. The occulted star will be Mag 12.3, so the occultation should be detectable. I used a 5x Teleview Powermate to give 6m focal length. See "Next Event" menu for more info.

(423) Diotima : Long Positive.

Diotima was at low elevation in Gemini near theta in the NW. The asteroid was monitored in frosty conditions (-2.5C) as it occulted a faint star at 4am. I was rewarded by a 29sec dimming as can be seen in the blue line.

2016-Jan 19
Lunar Occultation of Hyades Cluster

Two step events and one fade were captured by video at 50 fps. These were my first records of non-instaneous events during an occultation by the Moon. The light curve is from 70 Tau by analysis of the AVI with Limovie. The step duration was 400ms for near equal components separated by 0.1 sec arc.

14 observations from the UK campaign. This is just the RAW data plot

1970Nov 28 Purchase of an AE 6" F/8 mirror Peter Lancaster-Brown recommended Astronomical Equipments (AE) Luton. A 1/10 wave mirror and flat were purchase for £ 17-12-6p. The optics were used in wooden square latice tube on a alt-az mounting. Eyepieces were from Fullerscopes: Opposite: Eclipse 1973 with the 6" on the fore deck of the Mone Umbe.
