The Antihelion meteor shower may be observed this week:

The Anthelion radiant is centred at RA 01:36 Dec +10 in eastern Pisces, three degrees northwest of the fourth magnitude star Omicron Piscium. Expect to see two shooting stars per hour.
With an entry velocity of 30 km/sec, the meteors are medium-slow.
The radiant is large and diffuse.
The antihelion source is produced by debris from unknown objects orbiting similar to the earth.
The antihelion source is active all year from an area of the sky nearly opposite that of the sun. The centre of this source will move approximately one degree eastward per day and travels through many constellations over the course of a year. These meteors are therefore not named after just one constellation.
The best time to view them is after midnight.

Also, watch out for sporadic meteors. Their rates for the Northern Hemisphere are now reaching a plateau. Expect around 12 random meteors per hour during the morning hours
