1  General Category / Photography / Re: Photos by Moonlight on: August 31, 2011, 02:06:46 pm
They look good to me too Richard, I have tried this before at the coast using rocks, beaches and buildings and wondered why everything looked so flat or something and I came to the conclusion that bright moonlight kills beach photo opps because the scene looks like daytime after an exposure and with the moonlit sky so bright only a small number of stars can be seen to indicate that it was a night shot. I tried this with Dunluce Castle with Conor last year and we were very unhappy with the result. So, in my opinion, from my own experience, it would be best to re-shoot the scene again with weak moonlight or else on a very dark night and push out the exposure and see what results you get. On a dark night you could try 'painting' the rock with a torch to bring it out. These images remind me of a place on the Co. Antrim coast which looks incredibly like your location, I was planning on going there soon but really wanted a semi-dark or full dark sky for it. Would love to see night time showers with moonbows over the rocks in your images...that would look awesome. Autumn is not far away now so those times will be upon is of luck with it Richard, and the images still looks great to me anyway, I like the first lot and could imagine that being a great location to image a bright comet!

Goodbye Richard, I hope what ever happened which caused you to leave wasn't personal. Keep up the great photography, you are always welcome to come back anytime you want. I wish you the very best of luck. I haven't been on the forum for a while so I'm only seeing this now and I genuinely do feel saddened to see you go.

Clear skies and happy shooting.

A couple of this famous Temple on a glorious sunny convective evening before sunset near Downhill Beach at the north coast.

...and here's a pano of the Temple with multicell thunderstorms tens of miles away in the distance producing regular c-g lightning.

You are turning into a fantastic night sky photographer Anton!!, excellent star trail image and as Richard said, 10/10 for the composition  Smiley

I like it alot Anton, can't beat the contrasting warm and cold colours along with moving clouds to compliment a night sky scene - very attractive image  Smiley

Hey Anton, sorry for the delay in getting back to you, I love this image of the ISS and your car in the same frame, you must have had a great wide angle lens for that - impressive!. What you witnessed sounded like a sporadic fireball, fireballs can be extremely bright and also very low in the sky at times so you can get them pretty much anywhere in the celestal dome so well done on seeing it, a truly bright fireball is a thrilling and unforgettable sight, you will be hooked from now on and will be trying to catch one on camera  Smiley

Beautiful image Richard!, what a view  Smiley

Been busy lately and not home very much so sorry for the lack of posts recently. I was at the coast on quite a few occasions and saw some pretty decent sunset scenes. All are from Downhill Beach, lovely glitter path and sunset convective cloud reflections, even saw distant lightning over the sea.

Geomagnetic Forecast: The geomagnetic field isexpected to be at minor to major storm levels with a chance for severe storm periods as the effects of three CMEs are expected toimpact the Earths geomagnetic field early on 05 August. Active tominor storm levels are expected on 06 August. Unsettled to activelevels are expected on 07 August.

Thanks Richard for checking it out  Smiley

Tyler, congrats on the NLC captures, very nice wave structure there, brilliant to see NLCs appearing so far south in the US and I'm delighted you have ticked them off your list, now I'm sure you will be on full aurora alert on the nights ahead  Smiley
11  General Category / Weather & Atmospherics / Convective Outlook Ireland & UK - Thurs August 4th on: August 04, 2011, 12:08:43 am

Moderate Risk of Thunderstorms northern half of Eire 09Z-18Z

Slight Risk of Convective Showers (Some thundery) UK regions as per map 12Z-21Z

Fairly high risk of general thunderstorm activity over northern regions of Eire through Thurs as the occluded front wraps around the central low pressure system. Advancing upper trough enhancing lift for the whole region. Prime risk moderate hail and CG's.

Slight risk of post frontal isolated convective showers in the wake of the initial upper and surface cold front for parts of UK as per map. Some of these could develop some weak sferic activity. Though given the weak height falls in place there will be some uncertainties here. Upper shear profiles slightly more supportive than of late. Particular attention is given to the front left exit region of the jet stream which shows a strong divergent vector from 700 mb upwards. General dynamic lift could be asserted within the region of the southern most yellow risk box running from Bristol Channel through to Lincs. Whilst there is steady increase in vertical speed shear with height the general profiles look fairly straight lined at all levels with minimal surface convergence right across the board! Prime factor for risk of convection turning thundery will lie with the influence from the 500mb dry incursion. Credit: Tony Gilbert

Thanks for the kind words John, a novel lol - that's a new one for me, I must take note of that for future inspiration. Pity the season is ending however one good thing ending often opens the door to some new good thing...and this time its aurora season  Smiley
13  General Category / Weather & Atmospherics / Re: Thunderstorm Gust Front - July 7th on: August 03, 2011, 06:23:26 pm
Thanks John, looks like more storms on Thurs and weekend so fingers crossed for something cool happening.

Thank you John, she was a bit angry so I encouraged her back out into the sunny sky  Smiley

Thanks very much Richard, there's just been another major M-class flare and CME heading to Earth, we now have multiple rounds of aurora potential!
