Post by: Roman White on August 20, 2008, 12:46:21 pm
Just look what they forecast:

+37C in Poltava (and even more), and up to +42C in N, central, S Ukraine !  :o Africa become close to me  :D

Don't wonder if I'll melt on this weekend  ;) Although it must be clear and great for observations.

Yikes!

Trouble is, even if it's clear overnight, it'll be too hot to sleep during the day.

I have a friend heading to Ukraine today for a week with a group from his church, hope he packed the sun cream ;D

+40C isn't a trouble when it is dry (25% RH and lower). But when the air is humid (over 60% RH) even +30C makes a big trouble.
And what do you think about +25C at night? I think it's perfect. No chance to freeze  ;)

I'm curious: where exactly to Ukraine (if you know)? I don't think the sun cream is extremely necessary, but white and very thin clothes, also something to put on your head and few bottles of water is highly recommended.

Don't know Roman, but will try to find out, there's about 20 of them going, they go every year, mostly young people I think!

That looks intense Roman!. Be careful with the sunbathing. Don't know if those high temps will be any good for astronomy unless you can get a trans sky. In the other hand, with some moisture and instability you could get  some big storms.  :)

Found out Roman, they are going to Izmail, south west of you in Odessa Region. BTW, did you know that your city had an
asteroid named for it? (2983) Poltava (1981 RW2) discovered by Nikolay Chernykh in 1981 at CAO.

Martin,
It is surely better for astronomy then frost. First, all the electronic is working correctly at comfortable +15...+25C. Second, you will not even feel cold, and no additional clothes (so usual during autumn-winter-spring) is necessary. Third, it need much less time to get the outside temp. and the telescope temp. equal.
I do not hope for a big storms now. Last T-storm was here on July,26, and it is no rain here for 12 days in a row (!)

John, I have never been to Odessa region, but I know a bit about Izmail, and I'm sure it's a great place. There is a lot of historical monuments, churches, and, of course a great nature - Danube and many big lakes in the nearby. I hope they'll enjoy the trip! Also it would be nice to see some photos from your friend on the forum.  :)

Yes, I know about the asteroid (2983) Poltava.  :) Some time ago I have read an article in "Astronomic Calender" (published by Kiev Main Astr.Observatory) and there was mentioned not only this asteroid, but some more, which have been named in honour of famous ukrainian astronomers of XX century (including Chernykh).
But the asteroid itself is only 30 km dia. and in the nearest years it will be at 15-17 mag, so I'll never see it with my equipment.
