Spectacular aurorae seen in the last week

One of John's images from the M/S Midnatsol on January 24/25

The Sun has been very active this past week and John Mason, who is currently in Norway, reports that spectacular aurorae have been seen over the last few days. The images here were taken on the night of January 24/45. John writes:

I took a total of 508 images that night using a Canon EOS 450D with 10 mm
f/2.8 Sigma fish-eye.  All images were at 1600 ISO with exposure times
ranging from 1s to 15s during the night, depending on the brightness of
the auroral structures being imaged and the steadiness of the ship at the
time. During the most active part of the display exposures ranged from 1s
to 6s.

During the auroral display, I was observing from the aft of deck 9 on the
Hurtigruten ship M/S Midnatsol, which was sailing roughly northwards from
Tromsø to Oksfjord, via Skjervøy at the time.

There are more of John’s spectacular images below and John even made the Washington Post.

Jan 24/25 1824UT.

BAA observations refine asteroids orbit

BAA member Nick James was able to respond to an urgent request for observations of the newly discovered near earth asteroid 2012 BX34.

He was able to image the asteroid last night (January 26th) from Chelmsford, one day before its closest approach at around 15:30UT today.

Image of asteroid 2012 BX34 by Nick James

Nick writes:

Following an alert from ARPS director Richard Miles I observed this very small Near Earth Asteroid last night from Chelmsford. The asteroid had only been discovered the night before and is due to come within 0.2 lunar distance of the centre of the Earth at around 15:30 UTC today. It is probably only 4-5m across.

Observations using the Goldstone Solar System Radar were scheduled for this morning and so an urgent request went out for astrometry of this object to help refine the orbit. The attached image shows one of my observations. The asteroid was moving so fast (around 30 arcsec/min) that I had to take short exposures but it was relatively faint (around mag 17) so they needed to be stacked. This stack consists of 36 frames offset at the expected rate of the object. It is visible as a dot and the background stars are the trails. The gap was caused by a short break to take a couple of dark frames.

You can also read more about this asteroid on the BBC News website.
