Comet Lovejoy before Galaxy M63

Image Credit & Copyright: Damian Peach

Comet Lovejoy was captured last week passing well in front of spiral galaxy M63. Discovered only three months ago and currently near its maximum brightness, Comet Lovejoy can be seen near the Big Dipper from dark northerly locations before dawn with the unaided eye. An unexpected rival to Comet ISON, C/2013 R1 (Lovejoy), pictured above, is currently sporting a large green coma and a beautifully textured ion tail. Comet Lovejoy is now headed back to the outer Solar System but should remain a good site in binoculars for another few weeks. Conversely, spiral galaxy M63, lies far in the distance and is expected to remain stationary on the sky and hold its relative brightness for at least the next few million years.

Flaring activity was yesterday, December 1 and up to this moment today, December 2 limited to the C-level. The probability for C-flares is around 60%, for M-flares around 10% and almost no chance for X-flares. The candidates to populate the flare-club are NOAA AR 1907, 1908 and 1909. Geomagnetic conditions were quiet: K<3. This was due to a positive z-component of the interplanetary magnetic field (IMF). The IMF has although a relatively high value around 10nT. If the z-component turns
negative, unsettled conditions are possible. The solar wind speed is decreasing. A coronal hole will approach the central meridian tomorrow.

NOAA AR 1907 was responsible for the several B-flares and the 1 C-flare on November 30. We expect that the flaring situation stays as it is: a chance of 50% for C-flares, 20% for an isolated M-flare and almost zero chance for X-flares.

A partial halo CME was detected on November 30 coming into the field of view of SOHO/LASCO C2 around 14:00 UT in the SE. No on disk signature could be linked to this event. STEREO B EUI 195 indicates some flaring activity and a mass ejection around that time from a region near the centre
of the STEREO B solar images. This CME is determined as back-sided.The solar wind speed has reached 500 km/s since late November 30. The z-component of the interplanetary magnetic field (IMF) was mainly negative resulting in a planetary and local (Dourbes) K-index of 4 late November 30.
We expect the solar wind speed to decrease gradually. We expect quiet geomagnetic conditions with possible unsettled conditions (K=3) for the remaining part of December 1.
