Gamma Virginis , officially named Porrima is a binary star system in the constellation Virgo ~ it consists of two almost identical main sequence stars at a distance of about 38 light-years.

The “greatest illuminated extent” of Venus shows its largest illuminated area is the moment when the illuminated portion of the planet appears largest as seen from Earth ~ it’s at a point in its orbit where the illuminated portion visible from Earth is largest and it’s also closer to Earth, making it incredibly bright in the evening sky.

The Sickle in Leo looks like a backward question mark and represents the head and shoulders on the lion in the constellation Leo – Regulus is the brightest star in Leo and the Sickle.

The moon will pass the Beehive Cluster or Praesepe, a collection of stars also known as Messier 44 (M44).

From Milton Keynes, the Moon & Mars will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars in the constellation Gemini (The Twin)

Unfortunately the occultation will not be visible from Inverness to Cornwall, though it will be visible from Orkney Islands & Shetland Islands.

Good news for the deaf people

Live subtitles – that’s fantastic to hear
It’s heartening to see steps being taken
to make such events more inclusive.

For the first time, they provided live subtitles for the talks, making the event more accessible to a wider deaf audience, featuring 16 talks from leading astronomers and space scientists took place the weekend of 7th & 8th February 2025 at the conference hall – watch this space for next year (Friday 6th & Saturday 8th February 2026).

It was a great day to place the European AstroFest in London, most of deaf astronomers have considered coming along to see me for the guide, and they have made up to purchase their new equipment such as AM5N, SeeStar S50, filters and others.

Even if some don’t buy at the show, leaving a lasting impression is considering future purchasing decisions and when they are ready for that next purchase that is what the place is for.

Next one will be held at Practical Astro Show in Warwickshire on Saturday 15th March 2025, click here for more information.

The view was spectacular and there is even the Jewelled Handle, which can be seen only once a month for some hours.

The four largest moons of Jupiter, known as the Galilean moon (Io, Europa, Ganymede, and Callisto) are bright enough to be seen through binoculars ~ when observing Jupiter with a good pair of binoculars, you’ll notice this Callisto below the Jupiter’s southern limb.

Look out for the Moon tonight with Jupiter and following each night till Sunday ~ Mars lies close to a Moon on the early evening of Sunday 9th February at 6pm.

If you are at very north of Scotland, Orkney or Shetland, The Moon will pass in front of Mars.

This will create a beautiful celestial pairing ~ you can look for this event in the constellation Taurus, reaching high in the southern sky at 20:00 / 8pm.
