NEW METEOR SHOWER IN DRACO – Abstract: A new meteor shower on a JFC-type orbit has been detected in 2023 by the Global Meteor Network during the time interval 295.0° < λʘ < 299.0° (January 15–19) from a radiant at R.A. = 235° and Decl.= +61° with a geocentric velocity of 32.8 km/s. This radiant position is east from the known gamma-Ursae Minorids (GUM#0404) meteor shower which has its strongest activity when the new shower activity ends. The new meteor shower has been listed in the Working List of Meteor Showers under the temporary identification M2023-D2.

NEW METEOR SHOWER IN BOOTES – Abstract: A new meteor shower on a LPC-type orbit has been detected in 2022 by the Global Meteor Network during the time interval 282.41° < λʘ < 282.83° (2022, January 2–3) from a radiant at R.A. = 219° and Decl.= +28° with a geocentric velocity of 58.9 km/s. The new meteor shower has been listed in the Working List of Meteor Showers under the temporary identification M2023-D1.
