The nearly disconnected tail of Lovejoy blowing in the solar wind.   Something in the local space environment disrupted it within the last 2 days, it seems. Probably some kind of solar event like a CME or rogue magnetic field change caused this.

A big knot moving down the tail of Comet Lovejoy with the old tail partially disconnected and hanging on as best as it can.

Good transparency and cold temps helps to get good images at ISO 800.  5 minutes subs are not too noisy and stack up nicely.   This image is only 110 minutes of integration and could use more time, but it came out fine for an unmodified camera.

Moving further west each night, Comet Lovejoy Q2 continues to change and present a different profile each day.  It has gone back to a fan tail with streamers, much like it looked back on Jan 25 and Jan 16, 2015.    There is a pattern there, but the period remains elusive.
