Sitting at home

April 8th, 2020 by Ivan Boldyrev

I work from home for many weeks. Our employer has sent us home since middle of March…

Spending whole day at same place is bit frustrating, I only go to food store every other day.

The weather in Saint-Petersbourg is quite good today, and streets are not so empty as previous days.

I’m back again. Or not

March 27th, 2020 by Ivan Boldyrev

Update of my life: I’ve quit Yandex, moved from Novosibirsk to Saint-Petersbourg.

I almost forgot about astronomy, my current hobbies are French language, music, photography (including film) and programming (which is also my profession).

Hi, I’m back.

July 12th, 2014 by Ivan Boldyrev

Long time passed since last post.  My life has greatly changed: I’ve divorced (well, almost), changed my job — now I work at Yandex, Russia’s largest IT company, something like Russian Google.  I didn’t pay much attention to astronomy, alas (and other hobbies too) but I’ve rewritten Astronomers’ Map with Django framework (Python).

I have no idea what I will write about, but I hope I will be able to write something from time to time. 🙂

Novosibirsk Astrophysical center (“Large Planetarium”)

March 26th, 2012 by Ivan Boldyrev

There was a Planetarium day celebration at Large Planetarium on 24 of March.  This a view from Foucault pendulum tower:

The day was windy and rainy, but about 500 people (as estimated by one of Center’s employee) attended the event.

Novosibirsk Astrophysical Center was open today

February 8th, 2012 by Ivan Boldyrev

“Astophysical” means here “related to both astronomy and physics”, not “related to astrophysics”. This an educational center with planetarium, observatory, meteo station, Foucault pendulum etc.

Observatory has 360mm Ritchey–Chrétien by Astrosib and 200mm APOLAR refractor by NPZ.

See video at Russia 1 channel.

Meeting with amateur astronomers is planned tomorrow, and I am invited too, but cannot participate because of health problems 🙁
