Re: Earth grazer Leonid?? 6.25am Nov 18th

This long meteor was also recorded by four cameras of the NEMETODE network http://www.nemetode.org/ - one in Leeds, one in Basingstoke and two in Chelmsford. Their analysis classified it as a sporadic and derived this ground track:

Re: R Leonis and Venus

Sometimes you get a nice surprise like this entering the field of view as a planet moves along the ecliptic. R Leonis was due at maximum in mid September, so this is probably the brightest that its going to be seen in this apparition. The next maximum is due in July next year and so R Leonis will be...

Re: Perseids

Cloud got in the way at times on Perseid maximum night, but 2015 has provided my best spell of Perseid weather for many years: Aug 10-11 . 2144-0044UT (3 hours), LM 5.1-5.4. Clear sky 20 Perseids, 1 Delta Aquarid-S and 9 sporadics seen. Best meteor was a mag -2 Perseid at 23:18 UT, which travelled f...

Re: Lyrids

Yet more great work by Bill. Bill is not only looking to capture good spectra. He also aims to link his spectra to images of the same meteor captured by other observers. Triangulation can then be used to determine the former solar system orbit of the particle (meteoroid) that produced the meteor ......

R Scuti

If you are able to observe in the pre-dawn hours, you can currently see the variable star R Scuti fading. The star is visible in the south eastern sky and is at approx the same altitude above the horizon as Altair. From around mag 5.1 at the start of the month, R Scuti had faded to around mag 6.6 by...

Re: Submitting Observations to the Sections

I would say that the main requirements of a SPA section director are to be an enthusiast in the subject and to have a good idea where to look for answers when asked questions. In the case of the meteor section, I am purely a visual observer and have no experience of imaging. Consequently, I'm very g...

Re: R Leonis Bright

I've spotted R Leonis a couple of times recently.

Re: Fireball.Southern Delta Aquariid?

This fireball was also imaged by cameras in Chelmsford and at the South Downs Planetarium. Further details are available on the NEMETODE website http://www.nemetode.org/ (somewhat confusingly under the heading "30th July 2014: High over Heathrow" ), where is it concluded that it was a spor...

Mira and Chi Cygni

Saw Mira (Omicron Ceti) for the first time post-conjunction this morning. Its low altitude in the ESE made comparing its brightness with that of other stars tricky, but I estimated it to be mag 4.0 (slightly brighter than delta Cet). Maximum was predicted for early/mid June when Mira is unobservable...

Re: Variable stars in May : waiting to see chi Cygni

May 23-24: A couple of short lived partial clearances late in the night allowed a few VS estimates to be made: - R Scuti - at mag 5.6 - slightly brighter than a few days ago - T Cephei - at mag 6.9 - fading - chi Cygni - at mag 9.1 - brightening - Z Ursae Majoris - at mag 8.3 - brightening - S Ursae...

Re: May 24th meteors : what will be seen ?

Early indications are that although some Camelopardalid meteors were seen by observers in North America, the observed rates were somewhat lower than those predicted in advance.

Re: May 24th meteors : what will be seen ?

David Asher's analysis, which predicts peak activity at approx 07h GMT (8am BST), is now available on line at http://star.arm.ac.uk/~dja/209P/ .

The map below is from Rob McNaught's powerpoint that summarises this analysis and shows the areas that will be in darkness close to the predicted time.

Re: Upcoming Meteor Storm

Two key points - despite some sensationalised headlines in the media, a meteor storm (at around 07h GMT on May 24) is highly unlikely . Rates, briefly higher than those produced at the peak of the Geminids or the Perseids are possible for observers in North America, but are not guaranteed - virtuall...
