Hi all,
1. NLCs. The season for seeing Noctilucent Clouds (NLCs) runs from now until late July. Look low in the North for about two hours on either side of local midnight (allowing for longitude and summer time, i.e. local midnight in Ireland is approximately 01.20 to 01.40 clock time). They appear as silvery/white streaks and wisps shining brighter against the twilit background sky. The further South you are, the less chance you have of seeing them, as they will appear much closer to the horizon.
2. OM Events at Davagh Dark Sky Park: There will be some daytime moon and sun viewing sessions and a little 'AstronOMy' Club, plus other things related to the forest and so on. The page to check is: What's On | Guided tours at OM Dark Sky Park and Observatory
3. Our Place In Space | What's On The interactive scale model of the Solar System on Divis, just outside Belfast. See Scale model of solar system installed in Belfast hills (msn.com) For details of the Belfast events, see: Belfast | Our Place In Space.
4. Summer Solstice. The Sun reaches its most Northerly point on the ecliptic on 21 June at 09.13 (10.13 B/IST) marking the start of N. Hemisphere Summer.
5. Parade of the Planets, 20 to 28 June
During this period, all the naked eye planets will be visible together in the morning sky, in order of their distance from the Sun, although Mercury will be very low and you'll need binoculars to see it, except perhaps from the very far South of the island. The waning Moon will also be in the area, and on the mornings of 22 to 26 June, the Moon will also be in its correct order from the Sun, i.e. Mercury, Venus, Moon, Mars, Jupiter and Saturn.
Aesthetically, the nicest view will be on the 24th, with the waning crescent Moon about halfway between Venus and Mars.
To find Mercury, look about 10º below left of brilliant Venus, at an angle of about 8p.m. on a clock face. From the N of the island it won't rise until civil twilight has started, and it will be only mag -0.1 on the 24th, -0.2 on the 25th, -0.3 on the 26th, -0.4 on the 27th and -0.5 on the 28th, so binoculars or a wide-field telescope will be required.
On the 27th, Mercury will lie below the thin crescent Moon, and that will be your last good chance to find Mercury and to be able to see the Moon in the line-up.
Uranus and Neptune will also be in the line, but not in order, and you'll need binoculars or a telescope to see them.
6. Asteroid Day, 30 June.
See: ASTEROID DAY LIVE - Asteroid Day
7. ISS: A new series of morning passes starts on 1 July, transitioning into a mixture of morning and evening passes, and then evening passes only, continuing to 28 July. Details as usual on www.heavens-above.com
8. Space and Astronomy Webinar returns, 4 July. The next one will be at 7.30 on Tuesday 4 July. More details and links in next bulletin
9. On the Moon Again is Back on 8-10 July.
You are invited to join in a global project to bring observational astronomy to the streets of communities. On the Moon Again will take place from 8-10 July. For more information, see their website; to register your activity, fill out this form.
10. Davagh Dark Sky Park and Observatory is open, with pre-booking, and some restrictions.
See https://www.midulstercouncil.org/visitor/things-to-do/star-gazing/davagh-dark-sky-observatory , and https://www.facebook.com/omdarksky/ I'll post any updates here. Or phone 03000 132 132 for changing Covid-19 advice.
11. EASY TEASER:
What comes up sideways, but goes down vertically? No guesses yet, so - Clue: There's a pair. Another clue: "It's in your stars". Another clue: the coming up starts in the autumn, and the going down happens in the spring. Still no correct answers, so here's a final clue. It's a constellation .
12. DIFFICULT TEASER:
What's the connection between: a London Borough, a piece of rock, and another solar system body? No guesses yet, so – Clue: the other solar system body is a planet. Another clue: it's one of the 'terrestrial planets". Another clue: the residents of the borough seem to like using their car horns.
Please send all Teaser answers to me at my aol address terrymosel@aol.com
