Re: Possible evidence found for life on Venus

Following the undoubted success in detecting Phosphine in the atmosphere of Venus, a number of other teams have started a search for the following: Cannabis on the Moon, Heroin on Vesta, Salt on Ceres, Marmite on Mercury, Cocaine up Uranus, Syrup on Saturn, Intelligent life on Earth - this one seems...

Re: Uranus observed

This morning (August 29) I was following a Starlink satellite. It passed across an unmarked star, south of
29 Arietis. This turned out to be Uranus.
Satellite, Star and Planet were all around 6th magnitude.

Re: Doggy Astronomy !

Since this is about rainbows and dogs, it is appropriate to relate the following observation. About 6 months ago, on an unsettled winter's day, the Sun was shining brightly in the south, but was surrounded by extensive cirrus cloud. To the left of the Sun was an intense sundog, probably the brightes...

Preferences

Robin asked on the 'Observing' board: Any preferences, Stella? There is a difference between predicting the path of a chosen satellite, and trying to identify a satellite observed unexpectedly. All the prediction programs given in Robin's posting have their 'pros' and 'cons', so it is up to individu...

Re: Satellite or Meteor?

In order to identify a satellite, there are a number of things required to be reported accurately. 1. Observer's location -latitude and longitude if possible, but nearest large town or city may be sufficient. 2. Accurate date/time. Date in form of date-month-year. Don't use 'last night' or "On Thurs...

Re: Satellite or Meteor?

I get a perfect match, with 2019-93K, (44888) a Chinese ChangZeng 4B rocket that launched 2019 December 20.

At 22:43:21.0 U.T. (June 23) coincident with 74 UMa. from Latitude 53.0000 N, Longitude 2.1818W

This is from Stoke City, observer does not specify observing location.

Re: Starlink and New Moon

Yes, back in 1976 I managed to spot a 30 hour-old crescent.
Nowhere near a record, except that I had also seen the decrescent Moon 30 hours
BEFORE New, so that was just 60 hours between the 'before' and 'after' New.

Re: Starlinks "Darksat" not so dark

Let me tell you my tale. On January 27, I was scanning the southern part of the sky, when I spotted two satellites going east. I made magnitude estimates of them, without knowing their identity. The first one at 18:16:58.10 U.T. was magnitude +4.4. The second at 18:19:56.50 U.T. was magnitude +4.9. ...

Re: Betelgeuse

Comparing stars both red and blue,
Is a very hard thing to do,
I've looked for rhyme,
And taken my time,
But 'Purkinje Effect' ; I haven't a clue.
